Product Description

Tetramethylammonium hydroxide (TMAH) solution is a highly basic organic compound that is commonly used as a reagent and etchant in various industrial and laboratory applications. It has the chemical formula N(CH3)4OH and is also known as TMAOH.

TMAH is a colorless to yellowish liquid that is highly soluble in water and has a strong ammoniacal odor. It is typically supplied as a concentrated aqueous solution containing 25-50% TMAH by weight.

TMAH is widely used in the semiconductor industry as a photoresist developer and as an etchant for silicon dioxide and other materials. It is also used in the production of specialty chemicals, pharmaceuticals, and as a surfactant.

Like other highly basic substances, TMAH is corrosive and can cause severe burns and eye damage upon contact. Proper protective equipment, including gloves and goggles, should always be worn when handling this substance. TMAH should be stored in a cool, dry, well-ventilated area away from sources of ignition and incompatible materials.
