Trimethyl orthoacetate is used as a diols can be protected as their 1-methoxyethylidene cyclic acetals (2-methoxy-2-methyl-1,3-dioxolanes) by acid-catalyzed exchange. It is mainly used as the chemical intermediates of the medicine. Some of the other applications includes it is mainly used as chemical intermediate of pharmaceutical and agricultural chemicals, used for compound medical intermediates of vitamin B1, vitamin A1 and sulfanilamide organism, used for dye and spices industry, Medicine, agricultural chemicals, paint additives.
