4-Pentynoic acid (CAS: 1726-95-0, Formula: C5H6O2) is a terminal alkyne carboxylic acid used primarily as a versatile intermediate in organic synthesis. It is produced via the oxidation of specific alkynes or through decarboxylation pathways, serving as a critical building block for heterocyclic compounds and pharmaceutical scaffolds.
Store in a cool, dry, well-ventilated area away from oxidizers. Use appropriate PPE including gloves and eye protection due to corrosive properties. Avoid inhalation of vapors and ensure proper grounding during transfer to prevent static discharge.
