CATO manufactures Benvitimod impurity 9 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.
As a process- or degradation-related impurity, Benvitimod impurity 9 (CAS CATO-C4X-24459, C12H19O5P) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, Benvitimod impurity 9 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 274.25 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).
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.
