Description
Boc-O-Benzyl-L-threonine (CAS 15260-10-3, EC 239-304-5) is a protected amino acid derivative used as a building block in peptide synthesis, commonly referenced under the abbreviations BOC-THR(BZL)-OH and BOC-L-THR(BZL)-OH. It carries no assigned E-code. The compound falls under HS code 29242990 for customs classification purposes.
In pharmaceutical and biotechnology workflows, this compound serves as a key intermediate in solid-phase peptide synthesis, where the Boc group protects the amine and the benzyl group shields the hydroxyl during chain assembly. In personal care formulations, threonine-derived intermediates contribute antioxidant and antimicrobial activity, helping stabilise active ingredients and extend product shelf life.
Boc-O-Benzyl-L-threonine is supplied as a powder or crystalline solid and is subject to REACH registration requirements for EU procurement. Buyers should confirm purity specifications against internal quality standards, as grades vary between research-scale and GMP-compliant pharmaceutical manufacturing supply chains.
