Chemical Structure

Pyrazoloquinolone Impurity 3 CAS CATO-C4X-23893 chemical structure

Description

As a process- or degradation-related impurity, Pyrazoloquinolone Impurity 3 (CAS CATO-C4X-23893, C15H18N2O) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Pyrazoloquinolone Impurity 3 (C15H18N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

CATO manufactures Pyrazoloquinolone Impurity 3 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.
