Diazodinitrophenol, wetted with not less than 40 percent water or mixture of alcohol and water, by mass


Diazodinitrophenol (DDNP) was the first diazo compound produced; it was subsequently used to make dyes and explosives. It forms yellow crystals in pure form; however, the color of impure forms may vary from dark yellow to green to dark brown. It is soluble in acetic acid, acetone, concentrated hydrochloric acid, like most non-polar solvents and is slightly soluble in water. A solution of cold sodium hydroxide may be used to destroy it. DDNP may be desensitized by immersing it in water, as it does not react in water at normal temperature. Wikipedia
