Crisaborole Impurity 46 CAS 1194-02-1

Description

The occurrence of Crisaborole Impurity 46 is closely related to a nitrile group, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Crisaborole Impurity 46 (CAS 1194-02-1) is a certified pharmaceutical impurity reference standard with the molecular formula C7H4FN and a molecular weight of 121.11 g/mol.

Based on its molecular formula C7H4FN, Crisaborole Impurity 46 contains a nitrile group, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 121.11 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 Crisaborole Impurity 46 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.
