Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 292.35 g/mol gives Boc-Cys(Acm)-OH distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Boc-Cys(Acm)-OH (CAS 19746-37-3) is a high-purity analytical reference standard with the molecular formula C11H20N2O5S and a molecular weight of 292.35 g/mol.
Boc-Cys(Acm)-OH (C11H20N2O5S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures Boc-Cys(Acm)-OH under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
