Butalbital Impurity 7 CAS CATO-C4X-19837

Description

The occurrence of Butalbital Impurity 7 is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Butalbital Impurity 7 (CAS CATO-C4X-19837) is a certified pharmaceutical impurity reference standard with the molecular formula C11H15N3O4 and a molecular weight of 253.25 g/mol.

Based on its molecular formula C11H15N3O4, Butalbital Impurity 7 contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 253.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 Butalbital Impurity 7 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.
