Opis

General description

Esterate M (N,N-Dimethylformamide dimethyl acetal, DMFDMA) is an methylating reagent. It has been used in methyl esterification of carboxylic acid and also in one-step derivatization of amino acids into N,N-Dimethylaminomethylene methyl esters.

Application

It may be used in methylation of heterocyclic compounds which contains SH, NH, OH groups such as benzimidazole, naphth[2,3-c]imidazole, imidazo[4,5-c]-pyridine, purine, pyridine, pyrimidine, pyridazine and s-triazolo[4,3-b]pyridazine. It was used as derivatizing agent in a study to determine cocaine and benzoyl ecgonine in urine using GC with on-column alkylation.PMID 263947

Used in the preparation of formamidine derivatives, which are synthetic intermediates.

Used to catalyze the coupling of epoxides with carbon dioxide under solvent free conditions leading to cyclic carbonates.

Suitable for the derivatization of primary sulfonamides and trifluoroacetic acid.

Other Notes

Reagent for n-dimethylaminomethylene and methyl esters.
