CAS 6089-09-4: 4-Pentynoic acid

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. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Applications 4-Pentynoic Acid is a hypoglycemic agent shown to increase liver tyrosine aminotransferase and plasma corticosterone while decreasing blood sugar in rats. Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package References Fuller, R.W. et al.: Experientia, 29, 277 (1973);

4-Pentynoic acid used for ynenol lactones synthesis with 1-bromo-alkynes/Pd and macrolide production via ring-closing metathesis.

4-Pentynoic acid (4PA) is a natural product that has been shown to inhibit the growth of prostate cancer cells. It is a hydroxylated fatty acid and an oxidative metabolite of 4-hydroxybutyrate. 4PA inhibits the production of brain natriuretic peptide, which can be a predictor of cardiovascular disease. 4PA also has regulatory effects on the uptake of calcium carbonate by cells. The chemical structure of 4PA is similar to that of 2,5-dihydroxybenzoic acid, which inhibits monolayers on the surface of iron oxides. This similarity may lead to the formation of covalent linkages with the iron oxides, leading to particle formation and isolated yield.
