TCI C1332 Crotonaldehyde 2,4-Dinitrophenylhydrazone is the crystalline DNPH derivative of an α,β-unsaturated aldehyde frequently monitored in air quality and food analysis. Derivatization converts the reactive aldehyde into a stable, strongly UV-absorbing solid that is convenient to weigh and store. It serves primarily as a reference standard for chromatographic identification of carbonyl compounds and as a teaching example of carbonyl derivatization. AMI Scientific provides this TCI product in a compact laboratory pack size for analytical and educational laboratories in Indonesia.
