Chemical Structure

(1E)-1-(4-nitrophenyl)ethanone phenylhydrazone CAS 77635-72-4 chemical structure

Description

(1E)-1-(4-nitrophenyl)ethanone phenylhydrazone (C14H13N3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

(1E)-1-(4-nitrophenyl)ethanone phenylhydrazone (CAS 77635-72-4), molecular formula C14H13N3O2 and molecular weight 255.27 g/mol, is a CATO reference standard with documented purity and traceability.

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.
