On the analysis of long-chain alkane diols and glycerol ethers in biochemical studies

open access: yesJournal of Lipid Research, 1971
The chromatographic behavior of 1,2-, 1,3-, 1,4-, and 1,12-long-chain alkane diols and 1-O-alkylglycerols and their derivatives has been compared. Thin-layer chromatography on Silica Gel G gives poor separations of the 1,2-, 1,3-, and 1,4-alkane diols, O-
