Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 228.72 g/mol gives Benvitimod impurity 5 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Benvitimod impurity 5 (CAS CATO-C4X-24455) is a certified pharmaceutical impurity reference standard with the molecular formula C12H17ClO2 and a molecular weight of 228.72 g/mol.
The molecular framework of Benvitimod impurity 5 (C12H17ClO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
