It is soluble in water at 191 gm/L, also in ethanol, DMSO, methanol, chloroform, chloroform methanol mixture, and in dioxane 10 mg/L. This compound is used for material synthesis and is generally recognised as safe.[2]

Compounds in which the amide nitrogen is connected to another, and then doubly-bonded, are called isonicotinoylhydrazones.[3]
