3-HEXYN-1-OL Usage And Synthesis

Chemical Properties

CLEAR YELLOW LIQUID

Uses

3-Hexyn-1-ol is an unsaturated alcohol that, when subjected to stereoselective hydrogenation, produces cis-3-Hexen-1-ol (H295005), a compound that is important in the fragrance industry. 3-Hexyn-1-ol also exhibits antifungal properties against Aspergillus oryzae, a fungus that is used to produce fermented foods and beverages in Japan.

General Description

The stereoselective hydrogenation of 3-hexyn-1-ol was studied. Poly(N-vinyl-2-pyrrolidone)-stabilized Pd-nanoclusters showed an extraordinary catalytic performance in the selective hydrogenation of 3-hexyn-1-ol.
