4-(Difluoromethyl)-2-nitro-6-(trifluoromethoxy)nicotinoyl chloride CAS 1806780-74-4

Description

Compared with other compounds in its class, the molecular weight of 320.56 g/mol gives 4-(Difluoromethyl)-2-nitro-6-(trifluoromethoxy)nicotinoyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-(Difluoromethyl)-2-nitro-6-(trifluoromethoxy)nicotinoyl chloride (CAS 1806780-74-4), a certified reference material (molecular formula C8H2ClF5N2O4, MW 320.56 g/mol) for analytical method development and quality control.

4-(Difluoromethyl)-2-nitro-6-(trifluoromethoxy)nicotinoyl chloride (C8H2ClF5N2O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
