Description

Application

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

General description

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