Chemical Structure
Description
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 1-chloro-2-fluoro-3-nitro-5-(trifluoromethyl)benzene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 249.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO supplies 1-chloro-2-fluoro-3-nitro-5-(trifluoromethyl)benzene (CAS 101646-02-0), a certified reference material (molecular formula C7H8ClF4NO2, MW 249.59 g/mol) for analytical method development and quality control.
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.
