WebThis 2.0 M Triethylamine Acetate solution is used with OPC™ cartridges (Cat. No. 400771), for oligonucleotide purification. The Triethylamine Acetate solution comes in a … Triethylamine is commonly employed in organic synthesis as a base. For example, it is commonly used as a base during the preparation of esters and amides from acyl chlorides. Such reactions lead to the production of hydrogen chloride which combines with triethylamine to form the salt triethylamine hydrochloride, commonly called triethylammonium chloride. Hydrogen chloride may then evaporate from the reaction mixture, which drives the reaction. (R, R' = alkyl, aryl): gold standard whey sweetener
