REFERENCES

• Derivatizing agent for carbonyl compounds as their semicarbazones. Also used in heterocyclic synthesis. Semicarbazone formation has been used to separate carbonyl compounds from mixtures by adsorption onto silica gel from a hydrocarbon solution. Regeneration is by hydrolysis with oxalic acid: Tetrahedron, 37, 843 (1981).
