Khoom cim npe

(R)-(-)-1,2-Propanediol CAS 4254-14-2 yog dab tsi?

(R) - (-) -1,2-Propanediol yog cov xim tsis muaj xim rau daj ntseg daj pob tshab kua. (R) Cov pab pawg hydroxyl hauv cov qauv ntawm 1,2-propanediol muaj qee qhov nucleophilicity thiab muaj kev cuam tshuam rau kev hloov pauv nucleophilic cov tshuaj tiv thaiv nrog alkyl halides thiab acyl halides kom tau txais cov khoom sib xws ether thiab ester derivatives. Vim yog ob pawg hydroxyl nyob rau hauv txoj haujlwm nyob ib sab, lawv tuaj yeem ua rau muaj kev sib xyaw nrog aldehydes thiab ketones los tsim aldehydes lossis aldehyde compounds.
