1,5-Diphenylcarbazide Chemical Properties,Uses,Production

Chemical Properties

white crystals or powder

Uses

1,5-Diphenylcarbazideis a carbazide derivative used in the colorimteric determination of chromium as well as in the detection of cadmium, mercury, magnesium and aldehydes.

Uses

As indicator in titrating Fe; for the colorimetric determination of Cr, detection of Cd, Hg, Mg, aldehydes, emetine.

Uses

1,5-Diphenylcarbazide is used in the colorimetric determination of chromium, osmium as well as in the detection of cadmium, mercury, magnesium, emetine and aldehydes.

Definition

ChEBI: Diphenylcarbazide is a member of phenylhydrazines.

General Description

1,5-Diphenylcarbazide is a colorimetric reagent commonly employed in the determination of trace metals.

Purification Methods

A common impurity is phenyl-semicarbazide which can be removed by chromatography: ~8g in H2O is placed on a column (polyamide 6 powder, Macherey-Nagel-GmbH-Germany, washed several times with MeOH), eluted with H2O/MeOH/AcOH (1:3:0.04) at 7-8 drops/second, then eluted with the same solvent mixture but diluted 5 fold with H2O. The purification is followed by UV light at 280nm. The effluent is evaporated to dryness in vacuo at ~28o. [chromatography, IR & UV: Willems et al. Anal Chim Acta 51 544 1970]. Recrystallise it from EtOH by adding CCl4 to induce crystallisation, or AcOH to give a white crystalline powder which turns pink in air. It is air and light sensitive and should be stored in the dark under N2. [Beilstein 15 H 292, 15 IV 182.]

Q:How to prepare 1,5-Diphenylcarbazide solution for colorimetric testing?Theon - Jun 29,2026
A:For colorimetric testing, add 1.0 g 1,5-Diphenylcarbazide in 100 mL Aceton plus a drop acetic acid glacial or add 0.1 g in 100 mL Ethanol. It can be used as a redox indicator for colorimetric determination of chromium, mercury, lead, and determination of dichromate. The colorless (or faint white) indicator is oxidized and forms a vivid, brightly colored complex with the reduced metal ions.
