5 - Nitro - 2 - (2 - methyl - 4 - (N - ethyl - N - (2 - hydroxyethyl) amino) phenylazo) thiazole is an organic compound, and its preparation method is as follows:
The starting material needs to be prepared with 2 - methyl - 4 - (N - ethyl - N - (2 - hydroxyethyl) amino) aniline and 5 - nitro - 2 - thiazole diazo salt.
Prepared 5-nitro-2-thiazole diazo salt: Take 5-nitro-2-aminothiazole, dissolve it in an appropriate amount of inorganic acid, such as hydrochloric acid, and cool it to a low temperature, generally 0-5 ° C. Then slowly add sodium nitrite solution for diazotization reaction. This process requires strict control of temperature and sodium nitrite addition speed to prevent side reactions. During the reaction, 5-nitro-2-aminothiazole reacts with sodium nitrite, and the amino group is converted into a diazo group to generate 5-nitro-2-thiazole diazo salt.
Reproduction of 5 - Nitro - 2 - (2 - methyl - 4 - (N - ethyl - N - (2 - hydroxyethyl) amino) phenylazo) thiazole: The obtained 5 - nitro - 2 - thiazole diazo salt solution was slowly added with stirring containing 2 - methyl - 4 - (N - ethyl - N - (2 - hydroxyethyl) amino) aniline basic solution. This reaction is a coupling reaction. The diazo salt is coupled with the aniline derivative, and the diazo group is connected to a specific position on the aniline aniline ring to form an azo compound. The reaction process needs to maintain a suitable pH value and temperature, usually pH value is 8-10, temperature is 5-15 ℃, in order to ensure the smooth progress of the reaction and improve the yield and purity of the product.
After the reaction is completed, the reaction mixture is post-treated. The pH value can be adjusted by adding an appropriate amount of acid or base to promote the precipitation of the product. After filtering, washing, drying and other steps, the crude product is obtained. The crude product can be further purified by recrystallization, column chromatography, etc., and finally obtained a high-purity 5-Nitro-2 - (2-methyl-4 - (N-ethyl-N - (2-hydroxyethyl) amino) phenylazo) thiazole product. The whole preparation process requires strict control of reaction conditions and operating procedures to ensure product quality and yield.

I look at the "5 - Nitro - 2 - (2 - methyl - 4 - (N - ethyl - N - (2 - hydroxyethyl) amino) phenylazo) thiazole" you are inquiring about, which is a rather complex chemical substance. However, in the current market, its price is difficult to determine.
Because the market is volatile, the price of this chemical substance is subject to many factors. First, the price of raw materials fluctuates. If the various raw materials required for its preparation are scarce or the supply changes, the price will fluctuate. Second, the difficulty of the preparation process is also critical. If the synthesis of this substance requires delicate and complex processes and consumes a lot of manpower, material resources and time, the cost will be high and the price will not be low. Third, the market demand situation also affects the price. If many industries have strong demand for this substance, the supply will exceed the demand, and the price will rise; on the contrary, if the demand is low, the price may decline.
Furthermore, different suppliers and different purity requirements have very different prices. The higher the purity, the more difficult it is to prepare, and the higher the price. And in the era of "Tiangong Kaiwu", there were no such chemical substances, and the process technology at that time had not yet reached this level, so it is difficult to judge the current price based on ancient experience.
To know the exact market price of this substance, it is recommended to check the chemical product trading platform in detail, or consult a professional chemical raw material supplier to obtain accurate price information.

5 - Nitro - 2 - (2 - methyl - 4 - (N - ethyl - N - (2 - hydroxyethyl) amino) phenylazo) thiazole is an organic compound. However, many factors must be reviewed in detail about its safety.
From the view of chemical structure, it contains nitro, azo and other functional groups. Nitro, with strong oxidizing properties, or under specific conditions to initiate chemical reactions, the risk of heat and explosion is not impossible. The existence of azo groups cannot be ignored, and some compounds containing azo structures may form carcinogenic aromatic amines after metabolism or decomposition.
In terms of its production process, the selection of raw materials and the control of reaction conditions are closely related to safety. If the raw materials are impure or the reaction conditions are improper, the generation of impurities or the variation of product properties will cause a sudden drop in safety.
The use scenario is also critical. If used in industrial production, the concentration control of this substance in the working environment and the implementation of worker protection measures are all related to the safety and health of personnel. If used in consumer products, such as dyes, the residue in the product and the potential impact after long-term contact with the human body must be carefully evaluated.
And its environmental safety should not be underestimated. After entering the environment, the degradation pathway, degradation products, and impact on various components of the ecosystem of the compound need to be studied in depth. Or it accumulates in the environment due to refractory degradation, endangering biodiversity and ecological balance.
In summary, the safety of 5-Nitro-2- (2-methyl-4- (N-ethyl-N - (2-hydroxyethyl) amino) phenylazo) thiazole needs to be studied in detail from many aspects such as chemical structure, production, use and environment before a definite conclusion can be obtained to ensure human health and ecological environment safety.
