Safinamide Impurity 20 CAS 4397-53-9

Description

Compared with other compounds in its class, the molecular weight of 212.24 g/mol gives Safinamide Impurity 20 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Safinamide Impurity 20 (CAS 4397-53-9) is a certified pharmaceutical impurity reference standard with the molecular formula C14H12O2 and a molecular weight of 212.24 g/mol.

Safinamide Impurity 20 (C14H12O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 Safinamide Impurity 20 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.
