化学的特性6-Methyl-5-hepten-2-one is an important intermediate in the synthesis of terpenoids. Its odor properties are not impressive. It occurs in nature as a degradation product of terpenes. (Z)- and (E)-Tagetone, [3588-18-9], [6752-80-3], are major components of tagetes oil. Solanone [1937-54-8] and pseudoionone [141-10-6] are acyclicC13 ketoneswith a terpenoid skeleton. Solanone is one of the flavor-determining constituents of tobacco, and pseudoionone is an intermediate in the synthesis of ionones.
21 CFR 121.1164
1 - Materials that, under emergency conditions, can cause significant irritation.
2 - Materials that must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur. Materials would not under normal conditions form hazardous atmospheres with air, but under high ambient temperatures or under moderate heating could release vapor in sufficient quantities to produce hazardous atmospheres with air.
0 - Materials that in themselves are normally stable, even under fire conditions.
