Application:

δ-Valerolactone (CAS: 542-28-9) is a compound commonly used to synthesize copolyesters by means of lipase-catalyzed ring opening polymerization. δ-Valerolactone can be used as a monomer unit in the synthesis of poly(δ-valerolactone)s poly(conjugated ester)s via ring-opening polymerization. It can also be used as a starting material in the synthesis of (+)-Guadinomic Acid, Sodium δ-Hydroxyvalerate, Methyl δ-Hydroxyvalerate, and 5-Hydroxyvaleraldehyde. δ-Valerolactone is all-purpose chemical intermediate, which can be used in various fields. It can be used in the synthesis of pyran pyridine, cilostazol, witting reagent and epothifone anticancer drug in pharmaceutical industry, etc. Due to its good application flexibility, lower biological toxicity, more derivative compounds, easy polymerization and greatly increase the viscosity of coatings and other characteristics, δ-Valerolactone is widely used in polyesters, polyurethanes, special solvents, and coatings.
