Acetophenone impurity 13 CAS 41218-98-8 chemical structure

Description

CATO manufactures Acetophenone impurity 13 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.

Acetophenone impurity 13 (CAS 41218-98-8) is a certified pharmaceutical impurity reference standard with the molecular formula C17H18N2 and a molecular weight of 250.34 g/mol.

Based on its molecular formula C17H18N2, Acetophenone impurity 13 contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 250.34 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).

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.
