Product Description:

Dimethyl L-Cystine dihydrochloride is a derivative of the amino acid L-cystine, specifically its dimethyl ester in the form of a dihydrochloride salt. Structurally, it consists of two cysteine molecules linked by a disulfide bond, with both carboxylic acid groups esterified to methyl esters. This modification enhances its solubility and stability compared to the parent amino acid. This compound is primarily utilized in biochemical and pharmaceutical research as a building block for peptide synthesis and as a precursor for developing cysteine-containing peptides and proteins. Its protected ester form allows for selective deprotection and incorporation into complex molecular structures. Additionally, it serves as a standard or reagent in analytical chemistry for studying disulfide bond formation and redox chemistry in biological systems. As a versatile synthetic intermediate, it is also employed in the preparation of specialized organic compounds and drug candidates.
