Acetylenic Alcohols

High-purity acetylenic alcohols — a family of triple-bond diols and tertiary propargylic alcohols widely used as wetting agents, flow modifiers, and reactive intermediates in coatings, polymer, and ink systems. These molecules combine hydroxyl functionality with acetylenic unsaturation, providing a balance of reactivity and surface activity essential for modern formulations.
