Tetramethylammonium hydroxide

Description:
Tetramethylammonium hydroxide (TMAH) is a quaternary ammonium compound with the chemical formula (CH₃)₄NOH. It is typically encountered as a colorless, viscous liquid or as a solid in its pure form. TMAH is highly soluble in water and polar organic solvents, making it a versatile reagent in various chemical applications. It acts as a strong base due to the presence of the hydroxide ion, which allows it to readily deprotonate acids. TMAH is commonly used in the semiconductor industry for photoresist development and as a catalyst in organic synthesis. Additionally, it can serve as a surfactant and is utilized in various laboratory applications. However, it is important to handle TMAH with care, as it is toxic and can cause severe skin and eye irritation. Proper safety measures, including the use of personal protective equipment, are essential when working with this compound. Its stability and reactivity make it a valuable tool in both industrial and research settings.
