Used primarily as a reagent in organic synthesis, it serves as a precursor for generating malondialdehyde (MDA) in biochemical studies. MDA is a key marker for oxidative stress, making it valuable in research related to lipid peroxidation and cellular damage. Additionally, it is employed in the preparation of cross-linking agents for polymers and in the development of specialty chemicals for coatings and adhesives. Its role in analytical chemistry includes calibrating instruments for detecting and quantifying MDA in biological samples.
