Chemical Structure

Rosuvastatin impurity 245 CAS 147118-41-0 chemical structure

Description

The occurrence of Rosuvastatin impurity 245 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Rosuvastatin impurity 245 (CAS 147118-41-0) is a certified pharmaceutical impurity reference standard with the molecular formula C15H16FN3O and a molecular weight of 273.31 g/mol.

Based on its molecular formula C15H16FN3O, Rosuvastatin impurity 245 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 273.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

CATO manufactures Rosuvastatin impurity 245 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.
