Applications
4-Pentynoic acid is widely utilized as a building block for the synthesis of eight sequence-defined model oligomers. Due to its triple bond at terminal carbon, it is employed as an intermediate to produce biologically active compounds. It is used as a hypoglycemic agent, which increases liver tyrosine aminotransferase and plasma corticosterone while decreasing blood sugar in rats.

Solubility
Soluble in low polarity organic solvents. Soluble in water.

Notes
Keep the container tightly closed in a dry and well-ventilated place. Incompatible with bases, oxidizing agents and reducing agents.
