CAS 10424-65-4: Tetramethylammonium hydroxide pentahydrate
Description:Tetramethylammonium hydroxide pentahydrate (TMAH) is a quaternary ammonium compound with the chemical formula (CH₃)₄NOH·5H₂O. It appears as a colorless to pale yellow solid that is highly soluble in water, forming a strongly alkaline solution. TMAH is known for its strong basicity, which is attributed to the presence of the hydroxide ion. This compound is commonly used in various applications, including as a developer in photolithography processes in the semiconductor industry, as well as in organic synthesis and as a reagent in analytical chemistry. Due to its strong alkaline nature, TMAH can be corrosive and poses health hazards, necessitating careful handling and appropriate safety measures. It can also act as a surfactant and is utilized in some cleaning applications. The pentahydrate form indicates that it contains five molecules of water, which can influence its physical properties and stability. Overall, TMAH is a versatile chemical with significant industrial relevance, but it requires caution due to its corrosive characteristics.
