IPG-ester

Isopropylideneglycerol Solketal. Solketal is a protected form of glycerol with an isopropylidene acetal group joining two neighboring hydroxyl groups. The free hydroxyl groups of solketal can be esterified with a carboxylic acid to form the protected monoglyceride, where the isopropylene group can then be removed. The unprotected diol can then be esterified further to form either the di- or triglyceride
