BENZYLHYDRAZINE OXALATE
CAS32064-65-6
Benzylhydrazine oxalate (CAS 32064-65-6) is the oxalic acid salt of benzylhydrazine, a monosubstituted hydrazine used to introduce an N-benzyl hydrazine unit in organic synthesis. As a crystalline solid it is easier to weigh and store than the free base, and it is mainly used to build 1-benzylpyrazoles and other nitrogen heterocycles. KingPharm supplies benzylhydrazine oxalate for research and production with a batch-specific certificate of analysis.

Product Description
Benzylhydrazine oxalate is a salt of benzylhydrazine (PhCH2NHNH2) with oxalic acid, molecular formula C9H12N2O4. It provides the benzylhydrazine reagent in a solid, salt-stabilized form for synthetic chemistry.
In use, the free hydrazine is released in situ by adding a base. Its terminal NH2 group condenses with aldehydes and ketones to form hydrazones, and with 1,3-dicarbonyl compounds or oxaloacetate esters to close 1-benzylpyrazole rings, placing the benzyl group on a ring nitrogen.
Compared with the free base, which is an air-sensitive liquid, the oxalate salt is a solid that is simpler to handle and dose accurately. Compared with benzylhydrazine dihydrochloride, it introduces no chloride into the reaction, which can matter for chloride-sensitive steps; the choice between salts usually follows the base and solvent system of the route.
For procurement, buyers typically check assay, identity by NMR, the salt stoichiometry, and residual free hydrazine-related impurities, and confirm the specification against their process before scale-up.

Frequently Asked Questions
Benzylhydrazine oxalate or dihydrochloride: which to use?
Both deliver benzylhydrazine after neutralization; the oxalate adds no chloride, while the dihydrochloride may suit routes already using chloride salts, so choose by your base and solvent system.
How is the free hydrazine released?
Add a suitable base, such as a tertiary amine or sodium acetate, to the reaction mixture so the hydrazine is liberated in situ.
How should it be stored?
Keep tightly sealed in a dry place at room temperature, away from oxidizing agents.
