3-[1-(2-carbamoylethyl)-3-(4-chlorophenyl)-1h-pyrazol-4-yl]-2-cyanoprop-2-enoic acid CAS 1006493-20-4

Description

3-[1-(2-carbamoylethyl)-3-(4-chlorophenyl)-1h-pyrazol-4-yl]-2-cyanoprop-2-enoic acid (CAS 1006493-20-4), molecular formula C16H13ClN4O3 and molecular weight 344.75 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-[1-(2-carbamoylethyl)-3-(4-chlorophenyl)-1h-pyrazol-4-yl]-2-cyanoprop-2-enoic acid (C16H13ClN4O3) 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).

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.
