DCC CAS 538-75-0 Dicyclohexylcarbodiimide Purity > 99.0% (GC) Peptide Coupling Reagent Factory

DCC (N, N'-Dicyclohexylcarbodiimide, CAS: 538-75-0) yog siv nyob rau hauv peptide chemistry ua coupling reagent.Feem ntau yog siv rau cov khoom siv dag zog ntawm peptides Condensation ntawm amino acids.Piv txwv li, nyob rau hauv Fmoc-khoom synthesis, pawg carboxyl ntawm cov amino acid tsim ib qho amide daim ntawv cog lus nrog cov amino pawg ntawm lwm cov amino acid.Txhawm rau ua kom cov carboxyl pawg tau txais ntau dua rau kev tawm tsam ntawm nucleophiles, cov pa oxygen atom tsis zoo yuav tsum tau qhib rau hauv pab pawg zoo dua, thiab DCC ua lub luag haujlwm no.Cov pa oxygen atom ntawm pawg carboxyl ntawm cov amino acid ua lub nucleophile los tua cov pa roj carbon atom nyob rau hauv nruab nrab ntawm DCC molecule thiaj li DCC ua ke nrog cov carboxyl pawg los tsim cov qauv ester, ua rau nucleophilic nres ntawm cov amino pawg. yooj yim mus nqa tawm coupling reagent.

DCC yog siv rau synthesis thiab lub cev qhuav dej ntawm amikacin thiab amino acids.Nws yog ib tug zoo low-temperature biochemical dehydrating agent thiab kuj yog siv rau cov synthesis ntawm acids, anhydrides, aldehydes, ketones, thiab lwm yam. Nyob rau hauv Nyiv, dehydrating agents siv rau glutathione account rau 90% ntawm tag nrho cov noj.Thaum cov khoom siv los ua lub cev qhuav dej thiab condensing tus neeg sawv cev, nws tuaj yeem ua rau lub sijhawm luv luv ntawm chav sov, thiab cov khoom tom qab cov tshuaj tiv thaiv yog dicyclohexylurea.Txij li thaum lub solubility ntawm cov khoom nyob rau hauv cov organic hnyav yog heev me me, cov tshuaj tiv thaiv cov khoom yog ib qho yooj yim mus cais;Nyob rau tib lub sijhawm, vim tias cov khoom lag luam nyuaj rau yaj hauv dej, cov tshuaj tiv thaiv tseem tuaj yeem ua tiav txawm tias nyob rau hauv cov tshuaj aqueous.Cov khoom no kuj siv rau kev sib txuas ntawm peptides thiab nucleic acids.Kev siv cov khoom no tuaj yeem yooj yim tsim cov peptides los ntawm cov tebchaw nrog dawb carboxyl pawg thiab cov sib txuas nrog cov amino pawg dawb ntawm chav sov, thiab cov txiaj ntsig tau siab heev.Siv rau zus tau tej cov hypertensives thiab cyclic adenosine monophosphate.siv los ua biochemical reagent thiab organic synthesis dehydration condensing tus neeg sawv cev.
