Kodi (R)-(-)-1,2-Propanediol CAS 4254-14-2 ndi chiyani?

(R) - (-) -1,2-Propanediol ndi madzi owonekera opanda mtundu mpaka chikasu. (R) Magulu a hydroxyl mu kapangidwe ka 1,2-propanediol ali ndi nucleophilicity inayake ndipo amatha kukumana ndi ma nucleophilic substitution reactions ndi alkyl halides ndi acyl halides kuti apeze zotumphukira za ether ndi ester. Chifukwa cha magulu awiri a hydroxyl omwe ali moyandikana, amatha kukumana ndi ma condensation ndi aldehydes ndi ketones kupanga aldehydes kapena aldehyde compounds.
