What is the function of 2-Chloro-1-(4-Methylphenyl)-1-Propanone Cas 69673-92-3 ?
The invention relates to a method for preparing a key intermediate of closolprofen, 2-p-chloromethyl phenylpropionic acid. The method starts with toluene as raw material, through condensation with propionyl chloride to get p-methyl phenylacetone, and then through one-step bromination, carbonyl methoxylation, hydrolysis to get 2-p-methyl phenylpropionic acid, and finally chlorine generation to get 2-p-chloromethyl phenylpropionic acid. The invention obtains p-methylphenyl acetone from toluene and can directly obtain the key intermediate 2-p-methylphenyl propionic acid by one-step cooking method. The intermediate is in petroleum ether, and 2-p-chloromethyl phenyl propionic acid is obtained by light quantitative chlorination through chlorine gas, and finally chlorosolophen is synthesized. The production process is very short and the amount of waste water is small.
A preparation of chlorine SuoLuoFen key intermediates 2 ¨C to chlorine methyl phenyl propionic acid method, its characteristic is that, with toluene as the starting material, with propionyl chloride get to methyl phenyl acetone condensation, then through one-step bromide, carbonyl methoxyl, hydrolyzed by 2 ¨C methyl phenyl propionic acid, chlorinated finally get 2 ¨C chlorine methyl phenyl propionic acid.
Despite the rapid development of physical analytical methods, the application of organic reagents in analytical chemistry will not be reduced and may even be expanded. Not only because it does not need to use the large-scale complicated instrument, simple and rapid determination method for analysis of geological analysis, agriculture, medicine, environmental monitoring, etc will be effective for a long time, but also a lot of instrument analysis requires the use of organic reagents, such as adsorbent, extraction agent, chromogenic agent, fluorescent reagent, covert agent, etc.), which determines the organic reagents have long-term development prospects.
Our company has developed a variety of organic reagents, and before leaving the factory for a large number of tests to ensure quality. The chemical is both powerful and in large supply. If you are engaged in the organic reagent business, you may consider using our high-cost performance products.
