Triethyl Orthoformate (TEOF) is a reactive organic intermediate used extensively in organic synthesis. TEOF acts as a formylating agent and protecting group reagent for alcohols and amines, and serves as a building block for heterocyclic compounds, pharmaceuticals, and fine chemicals. Due to its low viscosity and high reactivity, Triethyl Orthoformate is ideal for condensation, acetal formation, and esterification reactions. Also referred to as OFE (ETHER), Ethylorthoformiat by TEOF manufacturers. We are among the trusted Triethyl Orthoformate (TEOF) suppliers worldwide, with reliable lead times and global supply capability.
