Properties: Plates from amyl acetate or water or 30% methanol, mp 119.5-121° (Whiffen, 1951); also reported as mp 115-116° (Johnson, 1966). [a]D29 -3.38° (c = 9.47 in methanol); [a]D25 +6.8° (c = 2 in H2O). Soly at 2°: water 2.1 g/100 ml, amyl acetate 7 g/100 ml. Also sol in chloroform, ether, acetone, methanol, ethanol, other common organic solvents except satd hydrocarbons. Relatively heat-stable, acid-stable, destroyed by boiling in aq soln at pH 7 for 1 hr, but shows no loss of activity after 15 min boiling. At pH 2 it is not destroyed by boiling for 1 hr. Rapidly inactivated at room temp by dil alkali with the formation of a volatile, fragrant ketone, 2,4-dimethylcyclohexanone. Extremely repellent to rats. LD50 i.v. in mice: 150 mg/kg (Leach).
