Product Description:

D-Cysteine hydrochloride monohydrate is the hydrochloride salt of the D-enantiomer of the amino acid cysteine, typically obtained as a monohydrate. It is a white to off-white crystalline powder. Unlike the naturally occurring L-cysteine, D-cysteine is a non-proteinogenic amino acid. Its primary applications are in biochemical and pharmaceutical research. It serves as a chiral building block for the synthesis of peptides and other bioactive molecules. It is also used as a precursor or intermediate in the preparation of various compounds, including potential drug candidates and enzyme inhibitors. In research settings, it can be utilized to study the stereospecificity of biological processes and enzymes. As a derivative of a fundamental amino acid, it also functions as a versatile chiral amine synthon in organic synthesis, particularly where the specific stereochemistry of the D-configuration is required.
