Abstract
The Paper, Chemical Agent Detector, 3-Way Liquid is used by the Canadian Forces for the detection of liquid chemical warfare agents and is supplied by Canada to many Western countries. Unfortunately, two of the three dyes used in the detector paper have been found to be mutagenic and thus a project was initiated to find non-mutagenic replacement dyes. The report describes the work leading to the replacement of dyestuff A2, which is currently used to detect G-type nerve agent liquid droplets. Candidate replacement dyes were either procured commercially or synthesized when not available commercially. Two good, non-mutagenic, replacement dyes for A2 have been found, namely Disperse Yellow 23 and p-ethoxyphenyl-azo-proportional to hydroxynaphthoic acid. These dyes were incorporated into paper, both alone and in the presence of the dyes used for detection of mustard and V-type nerve agents. TRUNCATED
