Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 290.76 g/mol gives s-(Benzamidomethyl)-l-cysteine hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
s-(Benzamidomethyl)-l-cysteine hydrochloride (CAS 33375-71-2) is a high-purity analytical reference standard with the molecular formula C11H14N2O3SHCl and a molecular weight of 290.76 g/mol.
s-(Benzamidomethyl)-l-cysteine hydrochloride (C11H14N2O3SHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), s-(Benzamidomethyl)-l-cysteine hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
