Applications & Uses
Uses
Reagent for the GC analysis of ritalinic acid. Alternative to Cl2CHCO2H for synthesis of purine rich oligomers.Lewis acid used in the preparation of geminal bis-peroxides from ketals and enol ethers with t-butyl hydroperoxide. Reagent used for the mild deacetylation of amines.
Uses
It was used in transmethylation of 1,2-Diacylglycerol (DAG) containing fractions which were purified using HPLC. It may be used to treat lipids during GC analysis done for determination of fatty acid methyl esters and dimethylacetals.
Uses
Trifluoro(methanol)boron is a reagent used for the GC analysis of ritalinic acid.
General Description
Boron trifluoride-methanol (BF-M) is an esterification reagent. BF-M is a powerful acidic catalyst for the esterification of the fatty acids. It easily cleaves acetylated dyes resulting in free amino groups. BF-M catalyzed trans esterification of vegetable oils forms biodiesel.
