CROTONALDEHYDE (15798-64-8, 4170-30-3, 123-73-9)
Crotonal · 2-butenal · 2-butenal, (E)-isomer
METHACROLEIN (4170-30-3, 78-85-3)
2-methylacrolein · methacrylaldehyde
Methacrolein, or methacrylaldehyde, is an unsaturated aldehyde. It is a clear, colorless, flammable liquid. Methacrolein is one of two major products resulting from the reaction of isoprene with OH in the atmosphere, the other product being Methyl vinyl ketone (MVK, also known as butenone).
phenylacetylene · phenyl-acetylene · phenylethyne
Phenylacetylene is an alkyne hydrocarbon containing a phenyl group. It exists as a colorless, viscous liquid. In research, it is sometimes used as an analog for acetylene; being a liquid, it is easier to handle than acetylene gas.
936-52-7 (99447-37-7, 936-52-7)
Cyclopropyl cyanide is the smallest carbon ring molecule with a cyanide group attached to it. It is mainly known by its involvement in experiments with microwave spectroscopy, rotational spectroscopy and photodissociation. In 1958, cyclopropyl cyanide was first studied for its rotational spectra, by Friend and Dailey.
Cyclopentene is a chemical compound with the formula C5H8. It is a colorless liquid with a petrol-like odor. It is one of the cycloalkenes.
Phenacyl bromide is the organic compound with the formula C6H5C(O)CH2Br. This colourless solid is a powerful lachrymator as well as a useful precursor to other organic compounds. It is prepared by bromination of acetophenone: C6H5C(O)CH3 + Br2 → C6H5C(O)CH2Br + HBr The compound was first reported in 1871.
