title: [Color reaction of chlorhexidine and proguanil with hypobromite].
abstract: Colour reaction of chlorhexidine and proguanil with hypobromite The antimalarial agent proguanil reacts with hypobromite to yield the red coloured (E)-3-[(4-chlorophenyl)imino]-N-isopropyl-3H-1,2,4-triazol-5-amine (6B). The structure of 6B was proven by X-ray. The red colour obtained by the test for the disinfectant chlorhexidinedihydrochloride Ph. Eur. with hypobromite is probably attributable to a corresponding chromophore.
