This acid is obtained by oxidising lO-chloro-l-methyl-5 10-dihydro-phenarsazine in a similar manner to that described for the 3-niethyl isomeride. It crystallises from acetic acid in colourless needles, melting with decomposition at 316° C. The sodium salt crystallises from 20 per cent, sodium hydroxide in fine, colourless needles. The hydrochloride crystallises in fine needles, melting with decomposition and turning emerald-green at 281° to 232° C.
