Description

trans-2-Nonenal 2,4-Dinitrophenylhydrazone is a high-purity chemical derivative primarily used as a reference standard and analytical reagent. This compound is critical for the accurate identification and quantification of carbonyl compounds, particularly aldehydes, in complex matrices. It is an essential tool for quality control laboratories, research institutions, and manufacturers in the flavor and fragrance, food safety, and environmental monitoring sectors requiring precise analytical methods.

Application

• Analytical Reference Standard: Used in High-Performance Liquid Chromatography (HPLC) and Gas Chromatography (GC) for the calibration and validation of methods targeting carbonyl compounds like trans-2-nonenal.
• Food & Beverage Analysis: Essential for detecting and quantifying off-flavor compounds, such as "cardboard" or "stale" flavors, in beer, oils, and packaged foods.
• Flavor & Fragrance Research: Serves as a key intermediate or standard in the synthesis and analysis of flavor molecules and aroma compounds.
• Environmental Testing: Employed in the analysis of airborne aldehydes and other carbonyl pollutants in environmental samples.
• Pharmaceutical Impurity Profiling: Used in the identification and control of aldehyde-related impurities or degradation products in drug substances and products.
• Material Science: Applied in studies of polymer degradation where carbonyl formation is a key indicator of oxidative breakdown.
