苯并氮杂卓并环衍生物类中间体亚硝胺杂质2 CAS CATO-C3D-262674 chemical structure

Description

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

苯并氮杂卓并环衍生物类中间体亚硝胺杂质2 (CAS CATO-C3D-262674) is a certified pharmaceutical impurity reference standard with the molecular formula C19H20ClN3O3S and a molecular weight of 405.90 g/mol.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 苯并氮杂卓并环衍生物类中间体亚硝胺杂质2 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 405.90 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 苯并氮杂卓并环衍生物类中间体亚硝胺杂质2 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.
