Semicarbazide is widely used in organic synthesis as a reagent for the identification and characterization of carbonyl compounds. It reacts with aldehydes and ketones to form semicarbazones, which are crystalline solids with distinct melting points, aiding in the identification of specific carbonyl groups. In the pharmaceutical industry, semicarbazide serves as an intermediate in the synthesis of various drugs, including those with anticonvulsant and antimicrobial properties. Its ability to form stable derivatives makes it valuable in drug development and research. Additionally, semicarbazide is used in the analysis of food products, particularly in detecting nitrofuran antibiotics, which are banned in many countries due to their potential health risks. It acts as a marker compound in testing for the presence of these antibiotics in food samples. In polymer chemistry, semicarbazide is employed as a cross-linking agent to modify the properties of certain polymers, enhancing their thermal stability and mechanical strength. This makes it useful in the production of specialized coatings and adhesives.
