About Tetra Methyl Ammonium Hydroxide Pentahydrate

Tetra Methyl Ammonium Hydroxide Pentahydrate

The chemical compound known as tetramethylammonium hydroxide pentahydrate (TMAH) has the formula (CH3)4NOH5H2O. It is a white, crystalline solid that can be dissolved in polar organic solvents as well as water. A frequent reagent in organic synthesis, TMAH is a potent base and is especially useful in the fabrication of silicon wafers for the semiconductor industry.

In the semiconductor industry, silicon wafers are etched using TMAH. During the lithography process, it serves as a developer to strip photoresist off the wafers. Because it is less corrosive and less likely to harm the underlying silicon, TMAH is recommended over other developers.

In analytical chemistry, TMAH is also employed as a reagent for silica and phosphate analysis in water samples. The content of hydrocarbons and other organic components in fossil fuels is also determined using TMAH during this research.
