Description

2-Methylbutanal 2,4-Dinitrophenylhydrazone is a high-purity analytical reference standard and chemical derivative. This compound is primarily valued for its role in the qualitative and quantitative analysis of carbonyl compounds, particularly aldehydes and ketones, via derivatization techniques. It is an essential reagent for research laboratories, quality control (QC) departments, and analytical service providers requiring precise identification and measurement of volatile organic compounds.

Application

• Analytical Chemistry Standard: Used as a certified reference material (CRM) for calibrating instruments and validating analytical methods for carbonyl detection.
• Carbonyl Compound Derivatization: Reacts with aldehydes and ketones to form stable, colored 2,4-dinitrophenylhydrazone (DNPH) derivatives, facilitating their separation and analysis by HPLC or GC.
• Air Quality & Environmental Monitoring: Employed in sampling cartridges for the determination of formaldehyde and other airborne carbonyl pollutants in indoor and outdoor air.
• Food & Flavor Analysis: Aids in the identification and quantification of Strecker aldehydes and other carbonyl flavor compounds in food products and beverages.
• Pharmaceutical Impurity Profiling: Supports the detection and characterization of aldehyde-based degradation products or impurities in active pharmaceutical ingredients (APIs) and drug products.
• Polymer & Material Science: Used to analyze residual monomers, oxidation products, or degradation by-products in polymeric materials.
