Formaldoxime is the organic compound with the formula H₂C=N−OH. It is the oxime of formaldehyde. A colorless liquid, the pure compound tends to polymerize into a cyclic trimer^[which?]. Aqueous solutions are stable as is the formaldoxime hydrochloride ([H₂C=N(−H)(−OH)]⁺Cl⁻). It is a reagent in organic synthesis for the conversion of aryl diazonium salts to aryl aldehydes.^[1]

It is generated by combining hydroxylamine and formaldehyde.^[2]
