Tetramethylammonium Bromide is highly demanded in the scientific laboratory for conducting different reactions by being used as a phase transfer catalyst. When it comes to measure the viscosity of aqueous solution of our offered chemical compound, it can be done at different temperatures like 20 degree Celsius, 25 degree Celsius and 30 degree Celsius. Our Tetramethylammonium Bromide is used for carrying out the synthesis of dithioacetals from acetals using transthioacetalisation within an environment that is solvent free.
