<p>The use of aniline derivs. of formula (I), and their salts with acids or bases, (1) as colour formers together with an oxidisable coupler in the Trinder reaction for detection of H2O2 (or systems which generate it) or peroxidase (or peroxidatively active cpds.) or (2) with an oxidising agent to detect aromatic amines (or systems which generate them) is new. R1 = H, lower alkyl or aryl; R2 = H or lower alkyl, opt. substd. by OH, NH2, COOH, lower alkoxycarbonyl, lower alkanoylamido, arylalkyl, aryl or -P(O)(R6)OR5, R3 = H, COOH or halo; R4 and R'4 = H, halo, COOH, lower alkoxy, or pref. at meta-position, lower alkyl; R1 plus R4; R2 plus R4 or R4 plus R'4, when on adjacent C atoms, may together form a 2-6C satd. or unsatd. hydrocarbon chain, opt. substd. by OH or OXO; R5 = H or lower alkyl; R6 = OH, lower alkoxy, lower alkyl or aryl. (I) are new cpds. provided that R5 = H and R6 is not lower alkoxy.</p> |
