Chemical Structure

Ozagrel Impurity 27 CAS 20511-20-0 chemical structure

Description

The occurrence of Ozagrel Impurity 27 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ozagrel Impurity 27 (CAS 20511-20-0) is a certified pharmaceutical impurity reference standard with the molecular formula C12H14O2 and a molecular weight of 190.24 g/mol.

The molecular framework of Ozagrel Impurity 27 (C12H14O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), Ozagrel Impurity 27 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
