2,5-Di(5-tert-butylbenzoxazol-2-yl)thiophene

2% 2C5 - Di% 285 - tert - butylbenzoxazol - 2 - yl% 29thiophene, the Chinese name is often 2,5 - bis (5 - tert-butylbenzoxazole - 2 - yl) thiophene. The main application fields of this compound are as follows:
One is the field of fluorescent whitening agents. For example, all kinds of fabrics in "Tiangong Kaiwu" pursue the effect of whitening, this compound can be used as a fluorescent whitening agent for fabric treatment. It can absorb invisible ultraviolet light, and then emit blue or blue-violet fluorescence, which complements the yellow light of the fabric itself, thereby significantly improving the whiteness and luster of the fabric, making the fabric look like a natural hand whitening, which is of great significance in the textile printing and dyeing industry.
The second is in the field of plastics. Just like the careful allocation of material color in "Tiangong Kaiwu", this compound is used in plastic processing to improve the appearance of plastic products. After addition, it can enhance the whiteness or brightness of plastic products, make plastic products more textured and aesthetically pleasing, and is widely used in plastic packaging, plastic building materials, etc., to improve the quality and market competitiveness of plastic products.
The third is in the field of coatings. "Tiangong Kaiwu" mentions the surface coating of many utensils. This compound is used in coatings to give coatings good fluorescent properties. It not only enhances the decorative properties of coatings, making coatings exhibit unique fluorescent effects under light, but also uses its fluorescent properties for coating quality detection and anti-counterfeiting, etc., to broaden the application scenarios of coatings.
The fourth is in the field of optical materials. The compound can be used to prepare optical materials due to its unique optical properties. For example, when used to make optical sensors, they can detect and sense certain substances or physical quantities in the environment by responding to specific wavelengths of light, just like the precise tools in "Tiangong Kaiwu" to accurately measure various materials, providing strong material support for the field of optical detection and analysis.

2% 2C5 - Di% 285 - tert - butylbenzoxazol - 2 - yl% 29thiophene is 2,5 - bis (5 - tert-butylbenzoxazole - 2 - yl) thiophene, which is synthesized as follows:
The starting material can be selected from 2,5 - dibromothiophene and 5 - tert-butyl - 2 - hydroxybenzoxazole. First, 5 - tert-butyl - 2 - hydroxybenzoxazole needs to be properly activated. It is reacted with a suitable halogenated reagent, such as p-toluenesulfonyl chloride (TsCl) in the presence of a base (such as triethylamine), so that the hydroxyl group is converted into a p-toluenesulfonate group, and this activated product has better exodus.
On the other hand, 2,5-dibromothiophene reacts with magnesium chips in a solvent such as anhydrous ether or tetrahydrofuran to prepare the corresponding Grignard reagent. Grignard reagents have strong nucleophilicity.
Subsequently, the activated 5-tert-butyl-2-p-toluenesulfonate ester benzoxazole is added to the reaction system containing 2,5-thiophene dimagnesium bromide. Under the protection of inert gas (such as nitrogen or argon), the reaction temperature is controlled in an appropriate range (such as 0 ℃ - 50 ℃), and the nucleophilic substitution reaction occurs. The thiophenyl negative ion in the Grignard reagent attacks the carbon atom where the p-toluenesulfonate group in the 5-tert-butyl-2-p-toluenesulfonate ester benzoxazole is located, forming a carbon-carbon bond, and the p-toluenesulfonate is left at the same time to obtain the target product 2,5-bis (5-tert-butyl benzoxazole-2-yl) thiophene. After the
reaction is completed, the excess Grignard reagent is quenched by conventional post-processing operations, such as adding a dilute acid solution, and then the product is extracted with an organic solvent (such as dichloromethane). After drying the organic phase with anhydrous sodium sulfate, the solvent is removed by distillation under reduced pressure, and finally further purified by column chromatography to obtain high-purity 2,5-bis (5-tert-butyl benzoxazole-2-yl) thiophene.

2% 2C5 - Di% 285 - tert - butylbenzoxazol - 2 - yl% 29thiophene is an organic compound. Its physicochemical properties are very important and are related to its many applications.
In terms of physical properties, this substance is often in a solid state due to intermolecular forces. Determination of its melting point can be a key indicator for identification and purity judgment. Usually, the melting point of this substance is relatively high. Due to its molecular structure, the conjugated system formed between benzoxazole groups and thiophene rings strengthens the intermolecular interaction, which requires high energy to disintegrate its lattice and convert it from a solid state to a liquid state.
When it comes to solubility, it exhibits a certain solubility in common organic solvents, such as chloroform, dichloromethane and other halogenated hydrocarbons. Due to the polarity of halogenated hydrocarbons and the partial polarity of the compound, the solute is dispersed in the solvent through the interaction of Van der Waals force between molecules and the dipole-dipole. However, in water, due to the limited polarity of the molecule as a whole and the presence of more hydrophobic groups, such as tert-butyl, it is difficult to dissolve.
Chemically, the conjugated structure of this compound gives it unique photophysical properties. It has significant fluorescence properties and can emit fluorescence under specific wavelength light excitation. This is because the electrons in the conjugated system are easy to excite and transition, absorb photon energy and reach the excited state, and then return to the ground state through radiation transition, accompanied by fluorescence emission. This fluorescence property makes it have great application potential in many fields, such as fluorescent probes, luminescent materials, etc.
Furthermore, the carbon atoms on the benzoxazole ring and thiophene ring in this compound can participate in the electrophilic substitution reaction under appropriate conditions. For example, under specific catalysts and reaction conditions, it can be replaced with electrophilic reagents to introduce new functional groups on the ring, thereby expanding its chemical derivativeness and laying the foundation for the synthesis of more functional materials.
In conclusion, the physicochemical properties of 2% 2C5 - Di% 285 - tert - butylbenzoxazol - 2 - yl% 29thiophene provide an important basis and broad prospects for its application in materials science, chemical analysis and many other fields.

I have not heard of the market price of "2,5-bis (5-tert-butylbenzoxazole-2-yl) thiophene". This compound is either rare in the market or a fine chemical for special purposes. Its price is high or low, related to multiple ends.
First of all, the difficulty of its preparation. If the synthesis method is complicated and rare reagents are required, the cost will be high and the price will be high.
Second discussion on the demand situation. If there is a large and urgent need in specific fields of scientific research and industry, but the supply is limited, according to the reason of supply and demand, the price will rise. On the contrary, if the demand is weak, the price may stabilize and low.
Furthermore, look at the market competition. If there are many competing for production, it is to compete for market share, or there is a strategy to reduce the price; if there are only exclusive or a few suppliers, the pricing power is on the other, and the price may be higher.
I have checked all the books and business records I know, but I have not obtained the actual price. To know the exact price, or to consult chemical raw material suppliers, chemical trading platforms, or to seek brokers specializing in the trading of organic compounds. In this way, the near real-time price on the market can be obtained.
