Description

Nsc97301 CAS NO 621-98-7 is a high-purity chemical compound, also known as 2,4-Dinitrophenylhydrazine (2,4-DNPH), which serves as a critical analytical reagent. Its primary value lies in its exceptional specificity for the qualitative and quantitative detection of carbonyl compounds, particularly aldehydes and ketones. This makes it an indispensable tool for researchers and quality control laboratories in the pharmaceutical, environmental monitoring, food and beverage, and industrial chemical sectors.

Application

• Carbonyl Compound Analysis: As a derivatizing agent for the HPLC and spectrophotometric determination of aldehydes and ketones.
• Environmental Testing: Detection and quantification of formaldehyde and other airborne carbonyl pollutants in indoor air quality assessments.
• Pharmaceutical QC: Used in stability testing and impurity profiling to identify and measure carbonyl-containing degradation products in APIs and finished drug products.
• Food & Flavor Chemistry: Analysis of Strecker aldehydes and other carbonyl flavor compounds or potential contaminants.
• Polymer & Material Science: Monitoring of oxidation products and degradation in polymers and industrial materials.
• Academic & Industrial Research: A fundamental reagent in organic synthesis and analytical method development for carbonyl chemistry.
