Cyproheptadine Impurity 2 CAS 2222-33-5 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.

CATO supplies Cyproheptadine Impurity 2 (CAS 2222-33-5), a pharmacopoeial impurity reference standard (molecular formula C15H10O, MW 206.24 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C15H10O, Cyproheptadine Impurity 2 contains a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 206.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

As a certified reference material (CRM), Cyproheptadine Impurity 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.
