Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 258.35 g/mol gives N-Acetyl-S-benzyl-d5-L-cysteine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies N-Acetyl-S-benzyl-d5-L-cysteine (CAS 1955496-81-7), a certified reference material (molecular formula C12H10D5NO3S, MW 258.35 g/mol) for analytical method development and quality control.
N-Acetyl-S-benzyl-d5-L-cysteine (C12H10D5NO3S) contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), N-Acetyl-S-benzyl-d5-L-cysteine 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.
