Usage

General Description

The chemical compound (2E)-1-(2,4-dinitrophenyl)-2-(4-nitrobenzylidene)hydrazine, also known as DNPH, is a yellow to orange crystalline substance with a molecular formula of C14H11N5O6. It is commonly used in analytical chemistry as a reagent for detecting carbonyl compounds. DNPH forms a colorful derivative when it reacts with aldehydes and ketones, allowing for easy identification and quantification using techniques such as high performance liquid chromatography (HPLC) or gas chromatography. Due to its potential as a respiratory irritant and potential mutagenic and carcinogenic properties, proper handling and disposal procedures are necessary when working with DNPH.

Correlation analysis of reactivity in the oxidation of substituted benzyl alcohols by benzimidazolium dichromate - A kinetic and mechanistic aspects

The oxidation of a number of para- and meta-substituted benzyl alcohols by benzimidazolium dichromate (BIDC), in dimethyl sulphoxide, leads to the formation of the corresponding benzaldehydes. The reaction is first order with respect to each BIDC and alcohol. The reaction is catalyzed by hydrogen ions and the dependence has the form kobs = a + b[H+]. The oxidation of [1,1-2H2]benzyl alcohol exhibited the presence of a substantial kinetic isotope effect. The rates of the oxidation of meta-substituted benzyl alcohols correlated best with Taft's σ1 and σR0 constants. The para-substituted compounds exhibited excellent correlation with σ1 and σRBA values. The polar reaction constants are negative. The rate of oxidation of benzyl alcohol was determined in nineteen organic solvents. An analysis of the solvent effect by multiparametric equations indicated the greater importance of the cation-solvating power of the solvents. Suitable mechanisms have been discussed.
