Pharmaceutical synthesis (core): Superior propionylating agent, used for the production of hormonal drugs and antibiotics such as cinoxatramycin propionate, testosterone propionate, betamethasone dipropionate, and clobetasol propionate; as well as acyl protection of pharmaceutical intermediates.
Flavors and specialty cellulose: Synthesis of propionate ester flavors; production of propyl acetate cellulose (CAP) for high-end coatings, inks, plastic films, and eyeglass frame materials.
Organic synthesis and dehydration: an efficient dehydrating agent for nitration and sulfonation reactions; resin/dye raw materials; an additive to prevent freezing of perchloric acid at low temperatures in non-aqueous titrations.
Pesticides and fine chemicals: Preparation of intermediates for herbicides and fungicides; Synthesis of surfactants and plasticizers.
