Chemical Structure

Pitavastatin Impurity 89 CAS CATO-C4X-103789 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Pitavastatin Impurity 89.

CATO supplies Pitavastatin Impurity 89 (CAS CATO-C4X-103789), a pharmacopoeial impurity reference standard (molecular formula C25H22FNO4, MW 419.44 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Pitavastatin Impurity 89 (C25H22FNO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 419.44 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 89 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.
