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.
Pyrazoloquinolone Impurity 2 (CAS CATO-C4X-23892) is a certified pharmaceutical impurity reference standard with the molecular formula C15H22N2O2 and a molecular weight of 262.35 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Pyrazoloquinolone Impurity 2 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 262.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
CATO manufactures Pyrazoloquinolone Impurity 2 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.
