4-戊炔酸

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.
