Chemical Structure
Description
Structurally, Pitavastatin Impurity 128 (C25H21FNO4Ca) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.5, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 458.52 g/mol, it falls into the moderately-high-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).
Pitavastatin Impurity 128 (CAS CATO-C4X-1037128) is a certified pharmaceutical impurity reference standard with the molecular formula C25H21FNO4Ca and a molecular weight of 458.52 g/mol.
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 Pitavastatin Impurity 128 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.
