2,4-DIMETHYL-1,3-THIAZOLE-5-CARBOXYLIC ACID - Introduction
2, a kind of organic compound, chemical formula is C7H9NO2S. It is a colorless to pale yellow crystalline powder.
2. Acid is often used as a spice and spice intermediate, which has a unique aromatic taste. It can be used in the production of products such as food, beverages, cosmetics and perfumes to increase their aroma. In addition, it can also be used as an intermediate in drug synthesis.
2. There are generally two preparation methods for acid:
1. Synthesis by thiazolyl: First, 2,4-dimethyl -1,3-thiazole is reacted with bromoacetic acid to obtain 2,4-dimethyl-1,3-thiazole -5-acetic acid. The resulting product is then reacted with a dilute acid solution to acid-hydrolyze the ethyl ester group to form 2, 3 acid.
2. Synthesis of halides: First, 2,4-dimethyl -1,3-thiazole is synthesized by the reaction of bromoethanone and 2-methyl thiourea. Ethyl 2,4-dimethyl-1,3-thiazole-5-acetate is then obtained by reacting 2,4-dimethyl -1,3-thiazole with bromoacetate. Finally, the resulting product is acidolysis to form 2, Ni acid.
Regarding the safety information of 2, acid, it has low toxicity, but still needs to pay attention to its use and storage. When using this compound, avoid direct contact with the skin and eyes, and avoid inhaling its dust or vapor. In case of accidental contact, rinse immediately with plenty of water and seek medical help. In addition, it should be stored in a dry, well-ventilated place, away from fire and oxidizing agents, to avoid fire or explosion. In handling and handling, should follow the correct safety procedures.
