Chemical Structure

苯并氮杂卓并环衍生物类中间体亚硝胺杂质5 CAS CATO-C3D-262677 chemical structure

Description

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5 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.

苯并氮杂卓并环衍生物类中间体亚硝胺杂质5 (CAS CATO-C3D-262677) is a certified pharmaceutical impurity reference standard with the molecular formula C12H14ClN3O and a molecular weight of 251.71 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide 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5 is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 251.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
