Oxalyl Dihydrazide from TCI is the dihydrazide of oxalic acid. Its molecule has two hydrazide groups joined through a single oxalyl unit. The compound is a solid and serves as a nitrogen-rich building block in the laboratory. Chemists use it to synthesize heterocyclic compounds, to form hydrazones and Schiff bases, and as a ligand in coordination chemistry. In analytical chemistry, oxalyl dihydrazide is a known reagent in colorimetric methods for determining copper, so its use goes beyond organic synthesis alone.
Chemists choose this material because both ends of the molecule carry a nucleophilic –NH–NH2 group that can react with aldehydes, ketones, or esters. Because the molecule is symmetrical, it readily forms bis-hydrazones and multidentate ligands that bind metal ions strongly. Its high nitrogen content also makes it of interest for research into energetic materials and blowing agents. As a solid, it stores well and can be weighed accurately for stoichiometric reactions, which helps give reproducible results from one experiment to the next.
In Indonesia, oxalyl dihydrazide is useful for analytical chemistry laboratories that develop spectrophotometric methods for determining metals in water samples. University research groups working on organic synthesis can use it as a starting material for nitrogen-containing heterocycles and hydrazone derivatives. Coordination chemistry laboratories can use it to prepare metal complexes with multidentate ligands. Materials science teams studying nitrogen-rich compounds may also include it in their research into energetic materials and blowing agents.
- Heterocyclic compound synthesis: the two reactive hydrazide groups let chemists build nitrogen-containing ring systems, which makes this compound a practical starting material for heterocycle construction.
- Hydrazone and Schiff base formation: the nucleophilic –NH–NH2 groups condense with aldehydes and ketones, and the symmetrical structure allows bis-hydrazone products to form readily.
- Coordination chemistry ligand preparation: its symmetrical structure supports multidentate ligands that bind metal ions strongly, which is useful for preparing and studying metal complexes.
- Colorimetric copper determination: oxalyl dihydrazide is a known reagent in colorimetric methods for copper, which supports spectrophotometric analysis of metals in water samples.
- Energetic material and blowing agent research: its high nitrogen content makes it a relevant candidate for exploratory studies of nitrogen-rich energetic compounds and blowing agents.
