(R)-(-)-1,2-Propanediol CAS 4254-14-2
(R) - (-) -1,2-Propanediol waa dareere hufan oo huruud ah oo aan midab lahayn. (R) Kooxaha hydroxyl ee qaabka 1,2-propanediol waxay leeyihiin nucleophilicity gaar ah waxayna u nugul yihiin inay maraan falcelinta beddelka nucleophilic ee alkyl halides iyo acyl halides si ay u helaan ether iyo ester derivatives. Sababtoo ah labada kooxood ee hydroxyl ee ku yaal jagooyinka ku xiga, waxay la kulmi karaan falcelinta uumiga aldehyde iyo ketones si ay u sameeyaan aldehyde ama xeryahooda aldehyde.
