Chemical structure of glycerol, also known as glycerine and propane-1,2,3-triol

Glycerol is an alcohol often used in the lab to avoid freezing and increase the density of liquids. Its standardised IUPAC name is propane-1,2,3-triol. It is also often referred to as glycerine or glycerin.

Uses of glycerol

  • Glycerol is used in many loading buffers to increase the density of the solution which enables good loading into already liquid filled wells of agarose and polyacrylamide gels. See agarose gel loading buffer and SDS sample buffer.
