Applications
2,2-Dimethoxypropane acts as a dehydrating agent. It also serves as an intermediate in the synthesis of vitamin E, vitamin A and various carotenoids such as astaxanthin. It is used as a reagent for the preparation of 1,2-diols, acetonides, isopropylidene derivatives of sugars, nucleosides, methyl esters of amino acids and enol ethers.
for example : Preparation of serial sections of arthropods using 2,2-dimethoxypropane dehydration and epoxy resin embedding under vacuum

PMSF does not inactivate all serine proteases. The effective concentration of PMSF is between 0.1 - 1 mM. The half-life is short in aqueous solutions (110 min at pH 7, 55 min at pH 7.5, and 35 min at pH 8, all at 25 °C). Stock solutions are usually made up in anhydrous ethanol, isopropanol, or corn oil and diluted immediately before use.C6H5CH2SO2F F.W. 174.20 - CAS #329-98-6 Show less (-) |
