yellow in color with a fruity odor. it is miscible in alcohol, ether,
and chloroform, and insoluble in water. it is obtained by chemical
synthesis. it is also termed 3,7-dimethyl-2,6-octadien-3-yl isobutrate.

Toxicity evaluation
In the rat, the acute oral LD 50
was reported to be > 36.3 g/kg (Jenner, Hagan,
Taylor, Cook & Fitzhugh, 1964). At this dose, the highest tested, toxic signs included depression,
wet fur and diarrhoea, but the surviving animals appeared normal after 1 wk. In the mouse, the
acute oral LD 50
was 151 g/kg (Jenner et al. 1964); animals were depressed soon after treatment
and excitable after 1 hr, with rough fur, and death occurred between 4 hr and 3 days. The acute
dermal LD 50
in rabbits was reported as > 5 g/kg (Moreno, 1974).
