Chemical Structure

Voriconazole Impurity 54 CAS 2617-47-2 chemical structure

Description

The occurrence of Voriconazole Impurity 54 is closely related to a phosphate ester group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Voriconazole Impurity 54 (CAS 2617-47-2) is a certified pharmaceutical impurity reference standard with the molecular formula CH5O4P and a molecular weight of 112.02 g/mol.

Voriconazole Impurity 54 (CH5O4P) contains a phosphate ester group. It is notably hygroscopic; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
