ENVIRONMENTAL TOXICOLOGY TOOLS & SERVICESDiphenylamine-d10 is intended for use as an internal standard for the quantification of diphenylamine (Item No. 24250) by GC- or LC-MS. Diphenylamine is an antioxidant and a pesticide.1 It inhibits the oxidation of α-farnesene in solution as well as in the coating of Granny Smith apples postharvest. Diphenylamine (1,000 ppm) prevents superficial scald in several varieties of apples when applied by dipping or wrapping postharvest.2 It is active against various benomyl-resistant or -sensitive isolates of the plant pathogenic fungus P. expansum (EC50s = <2-12.8 and 22.9-78.5 µg/ml, respectively).3 Diphenylamine (0.25%) induces mortality in sheep keds (M. ovinus).4 It has been found as a contaminant in various jellies and jams and seawater.5,6 Formulations containing diphenylamine have been used in the control of fungi and insects in agriculture and in the preservation of postharvest apples from scald.
