 |  | [Uses] 
 Diethylamine hydrochloride acts as a precursor of atrazine and lysergic acid diethylamide. It is also used as a reactant in the production of dyes and pharmaceutical compounds such as ranitidine. Further, it is used in Mannich reaction with paraformaldehyde. In addition to this, it is employed in the synthesis of diethylaminoethyl (DEAE) cottons by reacting with cotton cellulose in the presence of sodium hydroxide.
