Compared with other compounds in its class, the molecular weight of 315.39 g/mol gives Flusilazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Flusilazole (CAS 85509-19-9), molecular formula C16H15F2N3Si and molecular weight 315.39 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Flusilazole (C16H15F2N3Si) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
