Chemical Structure

Avanafil Impurity 24 CAS CATO-C4X-111824 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 518.40 g/mol gives Avanafil Impurity 24 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Avanafil Impurity 24 (CAS CATO-C4X-111824) is a certified pharmaceutical impurity reference standard with the molecular formula C23H25Cl2N7O3 and a molecular weight of 518.40 g/mol.

Avanafil Impurity 24 (C23H25Cl2N7O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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 Avanafil Impurity 24 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.
