General description

Toxicity of hexamethylenediamine dihydrochloride has been investigated[1]. Hexamethylenediamine dihydrochloride is also known as 1,6-diaminohexane dihydrochloride, 1,6-hexamethylenediamine dihydrochloride, 1,6- hexylenediamine dihydrochloride or 1,6-diamino-n-hexane dihydrochloride[2]. Hexamethylenediamine dihydrochloride on fusion of 1:6-di-(N3-cyano-N1-guanidino)-hexane yields polymeric diguanides[3].
