Product Technical Details

Product Overview

(S)-N-Boc-2-Amino-3-Methoxy-Propionic Acid, frequently recognized in the industry as Boc-O-Methyl-L-Serine or Boc-Ser(Me)-OH, stands as a critical protected amino acid derivative utilized extensively in the field of organic synthesis and peptide chemistry. This specialized building block features a tert-butoxycarbonyl (Boc) protecting group on the alpha-amino function and a methyl ether modification on the side chain hydroxyl group. Such structural configuration provides exceptional stability against racemization during coupling reactions, making it an indispensable reagent for the construction of complex peptide sequences and modified protein structures.

Our manufacturing process adheres to stringent quality control protocols to ensure consistent chemical integrity. The product is synthesized using advanced catalytic methods that maximize yield while minimizing impurities. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and optical rotation measurements, to guarantee compliance with international pharmaceutical standards. The high optical purity ensures that downstream peptide products maintain their desired biological activity and stereochemical configuration.
