Tetramethylammonium hydrogen sulfate

Description:

Tetramethylammonium hydrogen sulfate (TMAS) is an organic compound characterized by its quaternary ammonium structure, where a tetramethylammonium cation is paired with a hydrogen sulfate anion. It is typically a white crystalline solid that is soluble in water, making it useful in various applications, including as a phase transfer catalyst and in organic synthesis. TMAS exhibits hygroscopic properties, meaning it can absorb moisture from the environment. The compound is stable under normal conditions but should be handled with care due to its potential to release toxic gases upon decomposition. Its melting point and solubility characteristics make it suitable for use in both laboratory and industrial settings. Additionally, TMAS can participate in various chemical reactions, including nucleophilic substitutions and as a source of the tetramethylammonium ion in ionic liquid formulations. Safety precautions should be observed when handling this compound, as it may cause irritation to the skin and eyes.

Tetramethylammonium bisulfate hydrate

CAS: 80526-82-5

Tetramethylammonium bisulfate hydrate is an inorganic acid that is used as a reagent for analytical chemistry. It can be found in urine samples and has been used to determine the concentration of metal hydroxides in these samples. Tetramethylammonium bisulfate hydrate has been shown to inhibit the growth of bacteria, including polycarboxylic acid-producing strains, at concentrations of 100 mM. This property may be due to its ability to chelate metal ions required for bacterial growth. The magnesium salt of tetramethylammonium bisulfate hydrate is also used as a pharmaceutical dosage form. A chromatographic method involving co2 flow has been developed for the analysis of tetramethylammonium bisulfate hydrate.
