Groups of 50 male and 50 female B6C3F1 mice, eight to nine weeks of age, were given 0, 125 or 250 (males) or 0, 250 or 500 (females) mg/kg bw CI Acid Orange 3 (90% pure, < 1% impurities other than water and acetone) by gavage in corn oil on five days per week for 103 weeks and were sacrificed at 112-113 weeks of age. Mean body weights of high-dose mice were 5-11% lower than those of vehicle controls after week 74. Survival at the end of the study was: males--control, 38/50; low-dose, 25/50; and high-dose, 26/50; females--control, 23/50; low-dose, 23/50; and high-dose, 24/50. Treatment-related nephrotoxicity occurred in animals of each sex. Survival of males was reduced after week 100; this was attributed to the nephrotoxicity. There was no significant increase in the incidence of any tumor. Epithelial hyperplasia of the urinary bladder was observed in one low-dose and three high-dose females. One low-dose female had a squamous-cell carcinoma of the urinary bladder.

A process is described for making 1,4-diamino-2-methoxymethylbenzene of formula (I), or a physiologically compatible salt of 1,4-diamino-2-methoxy-methylbenzene, of formula (I):
1
wherein n is a number from 0 to 2 and HX represents an inorganic or organic acid. The process includes reacting 2-methoxymethyl-4-nitrophenol with a halogenacetamide to form 2-(2-methoxymethyl-4-nitrophenoxy)acetamide; rearranging the 2-(2-methoxymethyl-4-nitrophenoxy)acetamide to form 2-methoxymethyl-4-nitroaniline and then catalytically hydrogenating the 2-methoxymethyl-4-nitroaniline and, when n=1 or 2, subsequently reacting with the inorganic or organic acid, to form the 1,4-diamino-2-methoxymethylbenzene of formula (I), or the salt if n=1 or 2. Compositions and methods of dyeing hair containing the 1,4-diamino-2-methoxymethylbenzene or its salt are also described.
