Description

Ci 11875 CAS NO 6247-28-5 is a high-purity chemical compound, also known as 2,4-Dinitrophenylhydrazine (2,4-DNPH), widely recognized as a key derivatization reagent in analytical chemistry. Its primary value lies in its exceptional selectivity for carbonyl groups, enabling the precise detection, identification, and quantification of aldehydes and ketones in complex matrices. This product is essential for quality control and research laboratories across the environmental monitoring, pharmaceutical, food and beverage, and industrial chemical sectors, where accurate carbonyl analysis is critical for safety and compliance.

Application

• Derivatization agent for HPLC and GC analysis of aldehydes and ketones in air, water, and food samples.
• Preparation of carbonyl standards for calibration and method validation in environmental testing (e.g., OSHA, NIOSH methods).
• Reagent for quality control in pharmaceutical synthesis to monitor carbonyl-containing intermediates and impurities.
• Detection of off-flavors and spoilage markers (e.g., Strecker aldehydes) in food and beverage industries.
• Research chemical in organic synthesis for the preparation of hydrazone derivatives.
• Component in test kits and sensor development for on-site monitoring of volatile organic compounds (VOCs).
