Boc-Cys(4-MeOBzl)-OH

Product Overview

Boc-Cys(4-MeOBzl)-OH represents a critical protected amino acid derivative extensively utilized in the field of advanced peptide synthesis and pharmaceutical development. Identified by CAS number 18942-46-6, this compound features a tert-butyloxycarbonyl (Boc) protecting group on the alpha-amino function and a 4-methoxybenzyl (Mob) group protecting the thiol side chain of L-cysteine. This dual protection strategy ensures exceptional stability during complex multi-step synthetic routes, preventing unwanted side reactions such as oxidation or racemization.

Our manufacturing process adheres to strict quality control standards, delivering a product suitable for demanding research and industrial applications. The molecular formula C16H23NO5S and molecular weight of 341.42 g/mol define its chemical identity, making it a precise building block for constructing biologically active peptides and protein analogues.

Technical Specifications

Industrial Applications

This protected cysteine derivative serves as a fundamental intermediate in the synthesis of therapeutic peptides, diagnostic agents, and biochemical research tools. The Mob protecting group is particularly valued for its stability under acidic conditions while remaining removable under specific oxidative or strong acidic conditions, offering flexibility in orthogonal protection schemes.

• High stability during peptide coupling reactions.
• Prevents disulfide bond formation during synthesis.
• Compatible with solid-phase and solution-phase peptide synthesis.
• Ideal for producing complex pharmaceutical intermediates.
