Chemical Structure
Description
CATO supplies 1-(2-Chloroethylidene)-2-(2,4-dinitrophenyl)hydrazine (CAS 5135-80-8), a certified reference material (molecular formula C8H7ClN4O4, MW 258.62 g/mol) for analytical method development and quality control.
The molecular framework of 1-(2-Chloroethylidene)-2-(2,4-dinitrophenyl)hydrazine (C8H7ClN4O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
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.
