Boc-Cys-OH

Facilitate precise peptide synthesis and biochemical research with Boc-Cys-OH (CAS No.: 20887-95-0, CAT No.: SRCB-044), a high-purity N-tert-butoxycarbonyl protected L-cysteine derivative. This protected amino acid features a Boc group on the amino terminus and a free thiol group, making it a vital reagent in the synthesis of peptides and proteins that require cysteine residues for disulfide bond formation or thiol chemistry.

With a molecular formula of C₇H₁₃NO₄S and molecular weight of 205.25 g/mol, Boc-Cys-OH is typically a white to off-white crystalline powder, valued for its stability, high purity (≥98%), and solubility in common organic solvents such as DMF, DCM, and methanol. This compound is essential for solid-phase and solution-phase peptide synthesis, enabling selective coupling strategies and functional thiol handling in complex molecule assembly.
