Tetramethylammonium Price & Suppliers in India

Tetramethylammonium hydroxide (TMAH) is a powerful organic base and a quaternary ammonium salt. In its aqueous form, it is a colorless, clear liquid with a characteristic amine-like odor, while the anhydrous form appears as a hygroscopic solid. It is highly valued for its ability to act as a strong base without introducing metal ions into sensitive chemical processes.

In the Indian industrial landscape, TMAH is primarily sourced for the electronics and semiconductor manufacturing sector for wafer cleaning and photoresist development. Additionally, it serves as a critical phase-transfer catalyst in the synthesis of complex organic molecules, including pharmaceutical intermediates and specialty zeolites used in petrochemical refining.

When procuring TMAH in India, buyers should prioritize suppliers who provide high-purity grades with low metallic impurity profiles, especially for electronic applications. It is essential to verify the concentration levels (typically 25% or 10% aqueous solutions) and ensure that the packaging is compatible with the corrosive nature of the chemical to prevent degradation during transit.
