N-Nitroso Cyclizine EP Impurity A-d4 CAS 756524-88-6

Description

The occurrence of N-Nitroso Cyclizine EP Impurity A-d4 is closely related to deuterium isotope labeling, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies N-Nitroso Cyclizine EP Impurity A-d4 (CAS 756524-88-6), a pharmacopoeial impurity reference standard (molecular formula C5H7D4N3O, MW 133.18 g/mol) used for the identification and quantification of trace impurities in APIs.

N-Nitroso Cyclizine EP Impurity A-d4 (C5H7D4N3O) contains deuterium isotope labeling, an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

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.

CATO manufactures N-Nitroso Cyclizine EP Impurity A-d4 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.
