3-[(1Z)-2-Amino-1,2-dicyanoeth-1-en-1-yl]-1-(4-chlorophenyl)urea CAS 865658-74-8

Description

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.

CATO supplies 3-[(1Z)-2-Amino-1,2-dicyanoeth-1-en-1-yl]-1-(4-chlorophenyl)urea (CAS 865658-74-8), a certified reference material (molecular formula C11H8ClN5O, MW 261.67 g/mol) for analytical method development and quality control.

The molecular framework of 3-[(1Z)-2-Amino-1,2-dicyanoeth-1-en-1-yl]-1-(4-chlorophenyl)urea (C11H8ClN5O) 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).

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.
