glycerol usage and synthesis |
chemical properties |
clear, colorless, viscous liquid |
usage |
glycerol is used both in sample preparation and gel formation for polyacrylamide gel electrophoresis. glycerol (5-10%) increases the density of a sample so that the sample will layer at the bottom of a gel’s sample well. glycerol is also used to aid in casting gradient gels and as a protein stabilizer and storage buffer component. |

general description |
a colorless to brown colored liquid. combustible but may require some effort to ignite. residual sodium hydroxide (lye) causes crude material to be corrosive to metals and/or tissue. |
air & water reactions |
hygroscopic. water soluble. |
reactivity profile |
glycerine is incompatible with strong oxidizers. glycerol is also incompatible with hydrogen peroxide, potassium permanganate, nitric acid + sulfuric acid, perchloric acid + lead oxide, acetic anhydride, aniline + nitrobenzene, ca(ocl)2, cro3, f2 + pbo, kmno4, k2o2, agclo4 and nah. a mixture with chlorine explodes if heated to 158-176° f. glycerol reacts with acetic acid, potassium peroxide, sodium peroxide, hydrochloric acid, (hclo4 + pbo) and na2o2. contact with potassium chlorate may be explosive. glycerol also reacts with ethylene oxide, perchloric acid, nitric acid + hydrofluoric acid and phosphorus triiodide. |
health hazard |
no hazard |
