Description

Application

(R)-(+)-3-Butyn-2-ol may be used as a starting material in the multi-step synthesis of (R)-benzyl 4-hydroxyl-2-pentynoate.

Propargylic alcohols are important starting materials for new classes of second generation 5-lipoxygenase inhibitors.

Used in a ruthenium-catalyzed polymerization providing helical polyacetylenes.

Packaging
