Chemical Structure

Olmesartan impurity 99 CAS 1427168-36-2 chemical structure

Description

CATO manufactures Olmesartan impurity 99 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.

CATO supplies Olmesartan impurity 99 (CAS 1427168-36-2), a pharmacopoeial impurity reference standard (molecular formula C27H32N6O3, MW 488.58 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Olmesartan impurity 99 (C27H32N6O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. 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 488.58 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
