Chemical Structure

Ketoprofen Impurity 104 CAS CATO-C4X-1471104 chemical structure

Description

The occurrence of Ketoprofen Impurity 104 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ketoprofen Impurity 104 (CAS CATO-C4X-1471104) is a certified pharmaceutical impurity reference standard with the molecular formula C36H35NO7 and a molecular weight of 593.67 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Ketoprofen Impurity 104 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 593.67 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).

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 manufactures Ketoprofen Impurity 104 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.
