Eplerenone Impurity 12 CAS CATO-C4X-163012 chemical structure

Description

CATO manufactures Eplerenone Impurity 12 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.

Eplerenone Impurity 12 (CAS CATO-C4X-163012) is a certified pharmaceutical impurity reference standard with the molecular formula C23H28O5 and a molecular weight of 384.47 g/mol.

Eplerenone Impurity 12 (C23H28O5) contains a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
