CAS 75-59-2: Hidróxido de tetrametilamonio
Descripción:
Hidróxido de tetrametilamonio (TMAH) es un compuesto de amonio cuaternario con la fórmula química (CH₃)₄NOH. Se encuentra típicamente como un líquido incoloro y viscoso o como un sólido en su forma pura. TMAH es altamente soluble en agua y en disolventes orgánicos polares, lo que lo convierte en un reactivo versátil en diversas aplicaciones químicas. Actúa como una base fuerte debido a la presencia del ion hidróxido, lo que le permite desprotonar ácidos fácilmente. TMAH se utiliza comúnmente en la industria de semiconductores para el desarrollo de fotoresistencias y como catalizador en la síntesis orgánica. Además, puede servir como tensioactivo y se utiliza en diversas aplicaciones de laboratorio. Sin embargo, es importante manejar TMAH con cuidado, ya que es tóxico y puede causar irritación severa en la piel y los ojos. Las medidas de seguridad adecuadas, incluido el uso de equipo de protección personal, son esenciales al trabajar con este compuesto. Su estabilidad y reactividad lo convierten en una herramienta valiosa tanto en entornos industriales como de investigación.

CAS:Tetramethylammonium hydroxide is a strong base that is used in analytical chemistry for the quantitative determination of zirconium. It is an analytical reagent and has a pH of 14. Tetramethylammonium hydroxide forms complexes with metals such as zirconium and titanium, which are then analyzed by various methods such as atomic absorption spectroscopy, x-ray fluorescence spectroscopy, and inductively coupled plasma mass spectrometry. The optimum concentration of tetramethylammonium hydroxide for this application is approximately 25%. Tetramethylammonium hydroxide reacts with p-nitrophenyl phosphate to form a pink product, which can be detected by colorimetric analysis. This reaction also produces hydrogen fluoride gas, which must be removed before the solution can be used again. Tetramethylammonium hydroxide reacts with ammonium to form tetramethylammonium ion and water.
