Chemical Structure
Description
CATO supplies (3-Chloro-4-fluorophenyl)hydrazine hydrochloride (CAS 175135-74-7), a certified reference material (molecular formula C6H6ClFN2HCl, MW 197.03 g/mol) for analytical method development and quality control.
Owing to a nitrile group, fluorine/chlorine substitution, (3-Chloro-4-fluorophenyl)hydrazine hydrochloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 197.03 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
