Chemical Structure
Description
The occurrence of 2,4-Difluorophenylhydrazine Hydrochloride is closely related to a nitrile group, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,4-Difluorophenylhydrazine Hydrochloride (CAS 51523-79-6), a certified reference material (molecular formula C6H6F2N2HCl, MW 180.58 g/mol) for analytical method development and quality control.
2,4-Difluorophenylhydrazine Hydrochloride (C6H6F2N2HCl) contains a nitrile group, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
