General description
Trimethylphenylammonium hydroxide (TMAH) is a methylating reagent.
Application
Learn more in the Product Information
Suitable for the derivatization of amino acids, n-methyl and n-aryl carbamates and fatty acids, clonidine, and substituted phenylureas.
TMAH may be used as a 0.1 mole/litre solution in methanol to determine plasma concentrations of carbamazepine and other anticonvulsant drugs, including phenobarbital, diphenylhydantoin, primidone, and mephenytoin using Gas-Liquid Chromatography.
Other Notes
Reagent for n-methyl and methyl esters.
