Chemical Structure

2-[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]-N'-(6-fluoropyridin-2-yl)acetohydrazide CAS 691873-25-3 chemical structure

Description

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.

CATO supplies 2-[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]-N'-(6-fluoropyridin-2-yl)acetohydrazide (CAS 691873-25-3), a certified reference material (molecular formula C13H9ClF4N4O, MW 348.68 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 2-[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]-N'-(6-fluoropyridin-2-yl)acetohydrazide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 348.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
