Boc-Cys(Trt)-OH is a protected cysteine derivative used in Solid Phase Peptide Synthesis (SPPS). It features a t-butoxycarbonyl (Boc) group on the alpha-amino and a trityl (Trt) moiety on the thiol side chain to prevent oxidation. The molecular formula is C25H27NO4S with CAS No. 10694-85-6.
Store under inert atmosphere at -20°C to maintain stability. Use appropriate PPE including gloves and goggles due to potential skin irritation. Ensure compatibility with acidic deprotection conditions during synthesis.
