Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N-Acetyl-S-(2-cyanocarboxyethyl)-L-cysteine Bis(dicyclohexylamine) Salt (CAS 1356930-50-1) is a high-purity analytical reference standard with the molecular formula C9H12N2O5SC12H23N and a molecular weight of 441.59 g/mol.
The molecular framework of N-Acetyl-S-(2-cyanocarboxyethyl)-L-cysteine Bis(dicyclohexylamine) Salt (C9H12N2O5SC12H23N) is characterized by a steroid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), N-Acetyl-S-(2-cyanocarboxyethyl)-L-cysteine Bis(dicyclohexylamine) Salt 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.
