Diclofenac diethylammonium salt C18H22Cl2N2O2 ChemSpider diethylammonium salt, 78213-16-8. Overview Final Guidance The active substance is diclofenac diethylamine, an established active substance described in the BP , but not in the Ph. Eur. . The active substance is sparingly soluble in water and freely in ethanol 96 . Diclofenac diethylamine is a white to almost beige crystalline powder, which is not hygroscopic. Diethylamine - Wikipedia is an organic compound with the formula (CH3CH2)2NH. It is a secondary amine. It is a flammable, weakly alkaline liquid that is miscible with most solvents. It is a colorless liquid, but commercial samples often appear brown due to impurities. It has a strong ammonia-like odor.
