Beschreibung

Allgemeine Beschreibung

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.

Anwendung

Für die Katalyse der Kopplung von Epoxiden mit Kohlendioxid unter lösungsmittelfreien Bedingungen zu cyclischen Carbonaten.

Zur Herstellung von Formamidin-Derivaten, als Syntheseintermediate

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.

Suitable for the derivatization of primary sulfonamides and trifluoroacetic acid.

Sonstige Hinweise
