Product Usage

Pharmaceutical intermediates, generally used in organic synthesis.


Alpha-methyl cinnamaldehyde is a versatile fragrance commonly used in the fragrance of cosmetics, soaps, foods, etc. The Alpha-methyl streptopropane obtained by the further reaction thereof is used as a synthetic essence and also has a very good aroma. At the same time, α-methylcinnamaldehyde is also an important intermediate for the synthesis of the therapeutic drug epalrestat. As the number of diabetic patients increases, the demand for the drug increases, and the demand for intermediates also increases, and there is an urgent need to improve the process to improve quality.
