Pravastatin EP Impurity C CAS 159345-66-1 chemical structure

Description

Pravastatin EP Impurity C (CAS 159345-66-1) is a high-purity analytical reference standard with the molecular formula C24H38O7 and a molecular weight of 438.55 g/mol.

Pravastatin EP Impurity C (C24H38O7) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures Pravastatin EP Impurity C 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.
