Understanding the chemical intricacies of pharmaceutical intermediates is vital for anyone involved in synthesis and formulation. L-Threonine Benzyl Ester Hydrochloride (CAS: 33645-24-8), often abbreviated as H-Thr-OBzl·HCl, is a prominent example of such a compound, highly valued for its role in peptide synthesis and as a versatile chiral building block in organic chemistry. For professionals seeking to buy L-Threonine Benzyl Ester Hydrochloride, clarity on its synthesis and purity is essential.

The production of L-Threonine Benzyl Ester Hydrochloride typically involves the esterification of L-threonine with benzyl alcohol, followed by hydrochloride salt formation. This process requires careful control of reaction conditions to maintain the stereochemical integrity of threonine and to achieve high purity. The benzyl ester serves as a robust protecting group for the carboxyl terminus, which is critical for sequential amino acid addition in peptide synthesis without undesirable side reactions. A reputable pharmaceutical intermediate manufacturer will employ advanced purification techniques, such as recrystallization and chromatography, to ensure that the final product meets stringent specifications, commonly ≥98.0% purity as determined by High-Performance Liquid Chromatography (HPLC).
