Chemical Structure

Butylphthalide Impurity 15 CAS 3453-64-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 148.16 g/mol gives Butylphthalide Impurity 15 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Butylphthalide Impurity 15 (CAS 3453-64-3) is a certified pharmaceutical impurity reference standard with the molecular formula C9H8O2 and a molecular weight of 148.16 g/mol.

The molecular framework of Butylphthalide Impurity 15 (C9H8O2) 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 the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

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 Butylphthalide Impurity 15 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.
