Trt-L-Cys(Trt)-OH*DEA

Trt-L-Cys(Trt)-OH*DEA is a protected amino acid derivative based on L-cysteine, bearing a trityl (Trt) protecting group on the thiol side chain and a trityl (Trt) group on the amino acid framework as indicated by the Trt prefixes. The molecule contains an amino functionality and a carboxylic acid (-OH) while the sulfhydryl is masked as a thioether via Trt substitution, and the "*DEA" notation denotes an associated diethylamine (DEA) counterion or adduct form that affects handling and salt-related properties without changing the core protected structure. In peptide synthesis and related chemical biology workflows, the Trt-protected cysteine side chain provides chemoselective control of thiol reactivity during coupling steps and supports preparation of cysteine-containing peptide intermediates and conjugation-ready derivatives where thiol deprotection is performed at a later stage.

Designed for biological research and industrial applications, not intended for individual clinical or medical purposes.
