Ammonium Salts - Alfa Aesar

Ammonium salts are ionic compounds with the formula (R)4N + A -, where R is hydrogen, alkyl or aryl groups and A is an anion. When R is alkyl or aryl then they are referred to as quaternary ammonium salts. The quaternary ammonium cations are permanently charged, independent of the pH of their solution. Most of the ammonium salts are soluble in water and …

Ammonium Salt - an overview | ScienceDirect Topics

Ammonium salts of low molecular weight are soluble in water if the hydrocarbon portion of the amine is small. Because the nitrogen atom of an ammonium salt has a positive charge, ammonium salts are more water-soluble than amines. Drugs containing an amino group are often prepared as ammonium salts to improve their solubility in body fluids.
