Chemical Structure
Description
Structurally, Ketoprofen Impurity 106 (C14H11BrO) contains a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 275.14 g/mol, it falls into the medium-molecular-weight range. 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).
Ketoprofen Impurity 106 (CAS 59310-31-5) is a certified pharmaceutical impurity reference standard with the molecular formula C14H11BrO and a molecular weight of 275.14 g/mol.
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 106 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.
