詳細

詳細

1,2-Propanediol is an 1,2-alkanediol. It can be obtained from glycerol, via hydrogenolysis in the presence of Ru/C and Amberlyst ion-exchange resins.

1,2-Propanediol is an important petrochemical that can be prepared by the hydrogenolysis of glycerol. It is mainly used as a cryoprotectant for biological samples and also as an additive in food, cosmetic and pharmaceutical industries.

アプリケーション

1,2-Propanediol may be employed as a cryoprotective agent for the preservation (by cooling to sub-zero temperatures) of human embryos and and oocytes (human and mouse).
