Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(tert-butoxycarbonyl)-S-(3,4-dimethylbenzyl)-L-cysteine.
N-(tert-butoxycarbonyl)-S-(3,4-dimethylbenzyl)-L-cysteine (CAS 41117-66-2), molecular formula C17H25NO4S and molecular weight 339.45 g/mol, is a CATO reference standard with documented purity and traceability.
N-(tert-butoxycarbonyl)-S-(3,4-dimethylbenzyl)-L-cysteine (C17H25NO4S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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-(tert-butoxycarbonyl)-S-(3,4-dimethylbenzyl)-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.
