Used as a versatile reagent in organic synthesis particularly for formylation acetal formation and preparation of heterocyclic compounds. It is widely used in pharmaceutical agrochemical and specialty chemical manufacturing.

Primarily acts as a source of the formyl group (CHO) and as a dehydratingformalization reagent in chemical synthesis. It helps introduce functional groups and construct complex organic molecules.

Triethyl orthoformate also called ethyl orthoformate is a colorless volatile liquid with a characteristic odor. It is moisture-sensitive and reacts with water so it is generally handled under dry conditions.
