Chemical Structure

Voriconazole EP Impurity D(Voriconazole Related Compound B) CAS 137234-63-0 chemical structure

Description

As a process- or degradation-related impurity, Voriconazole EP Impurity D(Voriconazole Related Compound B) (CAS 137234-63-0, C16H14F3N5O) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Based on its molecular formula C16H14F3N5O, Voriconazole EP Impurity D(Voriconazole Related Compound B) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 349.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
