Chemical Structure
Description
CATO supplies 4-Bromo-3-(difluoromethyl)-5-fluoro-2-(trifluoromethyl)pyridine (CAS 1804847-74-2), a certified reference material (molecular formula C7H2BrF6N, MW 293.99 g/mol) for analytical method development and quality control.
Structurally, 4-Bromo-3-(difluoromethyl)-5-fluoro-2-(trifluoromethyl)pyridine (C7H2BrF6N) contains a nitrile group, fluorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 293.99 g/mol, it falls into the medium-molecular-weight range. 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.
