Chemical Structure

Rosuvastatin Impurity 32 CAS 123185-88-6 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Rosuvastatin Impurity 32 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 202.20 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).

Rosuvastatin Impurity 32 (CAS 123185-88-6) is a certified pharmaceutical impurity reference standard with the molecular formula C9H14O5 and a molecular weight of 202.20 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 Rosuvastatin Impurity 32 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.
