Opis ogólny

Trimethylphenylammonium hydroxide (TMAH) is a methylating reagent.

Zastosowanie

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.

A method has been established for the determination of four pharmaceutically active compounds (ibuprofen, ketoprofen, naproxen and clofibric acid) in water samples using dynamic hollow fiber liquid-phase microextraction (HF/LPME) followed by gas chromatography (GC) injection port derivatization and GC-mass spectrometric

It has been widely believed that drug entry from the middle ear into perilymph occurs primarily via the round window (RW) membrane. Entry into scala vestibuli (SV) was thought to be dominated by local, inter-scala communication between scala tympani (ST)

Our understanding of the perilymph kinetics of drugs depends largely on data obtained by the analysis of perilymph samples. Although a number of studies have demonstrated qualitatively that perilymph samples may be contaminated by cerebrospinal fluid (CSF), and some investigations
