Propargyl Alcohol (2-Propyn-1-ol) 98% / 99% / ≥99.5% CAS No. 107-19-7 Industrial & Pharmaceutical Grade

Propargyl Alcohol, available in 98%, 99%, and ≥99.5% concentrations, is produced via advanced copper-catalyzed addition of formaldehyde to acetylene, often as a co-product in the industrial synthesis of butynediol . It features a unique terminal acetylenic structure combined with a primary alcohol group, making it an exceptionally versatile building block for complex organic synthesis . As the simplest representative of acetylenic alcohols, it demonstrates remarkable reactivity and synthetic utility . Its high purity and consistent quality make it ideal for critical applications requiring precise chemical properties. Each batch is rigorously tested using GC analysis to ensure consistent quality meeting industrial and pharmaceutical standards .
