Usage

General Description

(2E)-2-[(2,4-dinitrophenyl)hydrazono]pentanedioic acid, also known as DNPH, is a chemical compound that is commonly used as a reagent for the detection and quantification of carbonyl compounds. It is a hydrazine derivative with a pentanedioic acid backbone and a 2,4-dinitrophenyl group attached to the hydrazone functional group. DNPH forms brightly colored derivatives with carbonyl compounds, making it useful for qualitative and quantitative analysis using techniques such as high-performance liquid chromatography (HPLC) or gas chromatography (GC). Additionally, DNPH can undergo a reaction with carbonyl compounds to form stable and crystalline derivatives, which is advantageous for analytical methods such as mass spectrometry. Overall, (2E)-2-[(2,4-dinitrophenyl)hydrazono]pentanedioic acid is a valuable tool for the detection and analysis of carbonyl compounds in various chemical and environmental samples.
