Chemical Structure

Rosuvastatin Impurity 27 CAS 1044518-75-3 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 Rosuvastatin Impurity 27.

Rosuvastatin Impurity 27 (CAS 1044518-75-3) is a certified pharmaceutical impurity reference standard with the molecular formula C13H22O5 and a molecular weight of 258.31 g/mol.

Structurally, Rosuvastatin Impurity 27 (C13H22O5) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 258.31 g/mol, it falls into the medium-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).

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 27 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.
