Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1798902-83-6 S-(5-Nitro-2-benzyloxy)phenyl-N-tert-butyloxycarbonyl-L-cysteine Methyl Ester.
1798902-83-6 S-(5-Nitro-2-benzyloxy)phenyl-N-tert-butyloxycarbonyl-L-cysteine Methyl Ester (CAS 1798902-83-6), molecular formula C22H26N2O7S and molecular weight 462.52 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1798902-83-6 S-(5-Nitro-2-benzyloxy)phenyl-N-tert-butyloxycarbonyl-L-cysteine Methyl Ester (C22H26N2O7S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 1798902-83-6 S-(5-Nitro-2-benzyloxy)phenyl-N-tert-butyloxycarbonyl-L-cysteine Methyl Ester 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.
