δ-Valerolactone (CAS: 542-28-9) yog ib qho khoom siv feem ntau siv los tsim cov copolyesters los ntawm kev siv lub nplhaib lipase-catalyzed qhib polymerization.δ-Valerolactone tuaj yeem siv los ua ib chav tsev monomer hauv kev sib txuas ntawm poly (δ-valerolactone)s poly (conjugated ester)s ntawm lub nplhaib-qhib polymerization.Nws tuaj yeem siv los ua cov khoom pib hauv kev sib txuas ntawm (+)-Guadinomic Acid, Sodium δ-Hydroxyvalerate, Methyl δ-Hydroxyvalerate, thiab 5-Hydroxyvaleraldehyde.δ-Valerolactone yog tag nrho cov hom phiaj tshuaj nruab nrab, uas tuaj yeem siv rau ntau yam.Nws tuaj yeem siv rau hauv kev sib txuas ntawm pyran pyridine, cilostazol, witting reagent thiab epothifone anticancer tshuaj nyob rau hauv kev lag luam kws, thiab lwm yam. Vim nws cov ntaub ntawv zoo yooj yooj yim, qis lom lom toxicity, ntau derivative compounds, yooj yim polymerization thiab zoo heev nce lub viscosity ntawm coatings thiab lwm yam ntxwv, δ-Valerolactone yog dav siv nyob rau hauv polyesters, polyurethanes, tshwj xeeb cov kuab tshuaj, thiab coatings.
