Colorless liquid.
Practically insoluble in water, soluble in alcohol, propylene glycol and oils.
Peculiar incense-like, resinous odor of moderate to poor tenacity.
This alcohol, rarely offered commercially, has been suggested for use in perfume compositions. It offers a rare type of odor, only occasionally needed. But it gives pleasant effects with Olibanum and Opopanax, with Elemi, etc. and with the herbaceous oils, Lavender, Lavandin, etc. If it were freely available at low cost, it could undoubtedly be used in modern soap perfumes of woody, fresh-aldehydic type, or the slightly medicated type.
Produced by several methods, e.g. from allyl-acetic ester by reduction to 4-Pentenol, which is oxidized to 4-Pentenal. The aldehyde gives the title alcohol via Grignard reaction with methyl magnesium iodide.
