Description

Acrolein 2,4-Dinitrophenylhydrazone is a high-purity analytical reagent and chemical derivative, specifically the 2,4-dinitrophenylhydrazone (DNPH) derivative of acrolein. This compound is critically important for the qualitative and quantitative analysis of aldehydes, particularly acrolein, in complex matrices. It is primarily needed by analytical laboratories, environmental testing facilities, and industrial quality control departments involved in air quality monitoring, polymer analysis, and chemical safety assessments.

Application

• Derivatization Agent for HPLC/GC Analysis: Used to convert volatile and reactive aldehydes like acrolein into stable, UV-absorbing derivatives for sensitive detection.
• Environmental Air Monitoring: Essential for sampling and analyzing airborne carbonyl compounds (e.g., from industrial emissions or combustion) according to standardized methods like EPA TO-11A.
• Quality Control in Chemical Manufacturing: Employed to monitor and quantify trace levels of acrolein or other aldehydes as impurities in solvents, monomers, and other chemical products.
• Polymer and Material Science Research: Used to study degradation products, such as acrolein release from overheated polymers or during thermal aging studies.
• Food Safety and Flavor Analysis: Applied in the detection of undesirable aldehyde compounds that can indicate spoilage or oxidation in food products and edible oils.
• Reference Standard and Calibration: Serves as a certified reference material (CRM) for instrument calibration and method validation in analytical chemistry.
• Toxicological and Safety Studies: Used in research laboratories to quantify exposure to toxic aldehydes in biological or environmental samples.
