Chemical Structure

Voriconazole Impurity 5 CAS 137234-75-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 383.76 g/mol gives Voriconazole Impurity 5 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Voriconazole Impurity 5 (CAS 137234-75-4), a certified reference material (molecular formula C16H13ClF3N5O, MW 383.76 g/mol) for analytical method development and quality control.

Based on its molecular formula C16H13ClF3N5O, Voriconazole Impurity 5 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 383.76 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 is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
