The physical properties of 5 + -hydroxyl-6-methyl-1H-indoline are as follows:
This substance is mostly solid at room temperature, and its appearance is often white to off-white powder. The texture is more delicate and uniform, and it may show a certain luster under light irradiation. It has a certain melting point, which can be used to identify its purity and characteristics. The specific value of its melting point varies slightly due to different experimental conditions and purity grades.
In terms of solubility, 5 + -hydroxyl-6-methyl-1H-indoline is insoluble in water, which is due to its molecular structure containing more non-polar groups and weak interaction with water molecules. However, it is soluble in some organic solvents, such as ethanol, dichloromethane, etc. In ethanol, with the increase of temperature, its solubility will increase, showing a better dissolution and dispersion state; in dichloromethane, it can dissolve relatively quickly to form a uniform solution system.
This substance has certain stability, but it will also change under certain conditions. For example, long-term exposure to strong light, high temperature or high humidity environment may cause oxidation reactions to occur, causing its color to gradually darken, from the original white or off-white to light yellow or even darker color, which in turn affects its quality and chemical activity. At the same time, if it comes into contact with some substances with strong oxidizing or strong reducing properties, it may also initiate chemical reactions and change its chemical structure and physical properties. In addition, 5 + -hydroxyl-6-methyl-1H-indoline has a certain odor, which is not strong and pungent, but a special organic compound can still be sensed when smelled closely.

The synthesis of 5-bromo-6-methyl-1H-indole-2-carboxylic acid is a key research in organic synthesis. To obtain this compound, several classical routes are often followed.
First, using o-nitrotoluene as the starting material, bromine atoms are introduced at suitable positions through bromination reaction. This step requires fine regulation of the reaction conditions, such as temperature and catalyst dosage, to ensure that bromine atoms fall precisely on the target check point. Subsequently, by reduction reaction, nitro groups are converted into amino groups, and many reducing agents are available, such as the combination of iron filings and hydrochloric acid. However, different reducing agents have their own advantages and disadvantages, which need to be weighed according to the actual situation. Then, the intermediate containing amino and bromine undergoes a condensation reaction with appropriate carboxylic acid derivatives to form the indole ring system. In this process, factors such as the reaction solvent and the type of base have a great impact on the reaction process and yield.
Second, phenylhydrazine and β-ketoate can also be used as starting materials. First, phenylhydrazine and β-ketoate undergo a condensation reaction to form a hydrazone intermediate. This reaction condition is relatively mild, but it is necessary to pay attention to the molar ratio of the reactants to optimize the reaction. Subsequently, under acidic or basic conditions, hydrazone is promoted to undergo intramolecular cyclization to construct the indole structure. Finally, through a series of functional group transformations, methyl and bromine atoms are introduced, and the indole ring is carboxylated at a specific position to obtain the target product 5-bromo-6-methyl-1H-indole-2-carboxylic acid.
The synthesis process requires strict reaction conditions, and the yield and selectivity of each step depend on the purity and yield of the final product. Chemists need to rely on their exquisite skills and rich experience to skillfully regulate the reaction in order to efficiently prepare this compound.

5-Methyl-6-methyl-1H-indolopyridine, this product is not suitable for the market price, and the price is low. Its price often fluctuates due to various factors.
One of the reasons is that the local area is the main reason. If it is a place where it is self-sufficient, and its sources are abundant and the production is convenient, the cost may be reduced, and the price is also low. However, if the land is biased, it is not easy to collect or improve, the cost is high, and the price is rising.
Second, the degree of improvement also affects the price. If it is high, rare, and the quality is excellent, it is mostly used in the field of high-end or refined chemical products. On the contrary, if the product is not refined, it contains a lot of energy, and it is used for general industrial purposes, and the cost is low.
Third, the supply and demand of the market are also low. If the demand is high, the demand is greater than the supply, and the price is often higher. If the market is low and the supply is low, the merchant will sell it, or reduce the price in order to sell.
Fourth, the policy law and the city's control also have an impact. If the method is low, the production and circulation are limited, the cost increases, and the price is also affected.
Roughly speaking, the price of this compound may vary from 10 gold to 100 gold per gram, and it still needs to be sold in the market.

This medicine should be placed in a cool, dry, well-ventilated place, and should be avoided from direct sunlight to prevent it from deteriorating and failing due to factors such as light, high temperature, and humidity. The ambient temperature should be kept within a more appropriate range, not too high or too low, too high will easily cause changes in its composition, and too low may affect its chemical stability. Relative humidity also needs to be controlled. Excessive humidity may cause the drug to absorb moisture and cause mildew and other problems; too low humidity may cause the drug to dry and crack, affecting its quality.
At the same time, this medicine should be placed separately from other items, especially away from odorous substances and substances that may undergo chemical reactions, to prevent odor or chemical changes, which may damage the efficacy of the drug. The storage place should be out of the reach of children to avoid accidental ingestion and accidents. And it needs to be used within the specified period. Once it exceeds the valid period, it must not be used again to ensure the safety and efficacy of the medication.
