Chemical Structure

DBCO-CONH-S-S-NHS ester CAS 1435934-53-4 chemical structure

Description

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.

DBCO-CONH-S-S-NHS ester (CAS 1435934-53-4) is a high-purity analytical reference standard with the molecular formula C28H27N3O6S2 and a molecular weight of 565.66 g/mol.

The molecular framework of DBCO-CONH-S-S-NHS ester (C28H27N3O6S2) 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. 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).

CATO manufactures DBCO-CONH-S-S-NHS ester 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.
