Diazodinitrophenol: History, Standards & Products

Diazodinitrophenol (DDNP) was one of the first diazonium or diazo compounds ever 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…
