Product Name: Tetramethylammonium hydroxide

Abbreviated name: TMAH

Item No.: SolverPI-Monomer TMAH

CAS No.:75-59-2

EINECS:200-882-9

Molecular formula:C4H13NO或(CH3)4NOH

Relative Molecular Mass:91.23

Constitutional Formula:

Physicochemical Property:

The product has the smell of Ammonia,it’s a strong alkaline and easy to assorb the CO2,It can be made to the solution with water(Acohol).The tetramethylammonium hydroxide with 5 crystal water is acicular crystal colorless and diliquescence.The melting point is 63℃.The boiling point is 120℃。It will decomposite to trimethylamine and methanol when heating to the biling point.The density of the product is 1.00(25/4℃),and it’s a alkali mater with Strong corrosive.Keep the packing seal.It’s easy moisure absorption if expose in the air.The decomposition point is 134℃.We call it “temporary catalyst”due to it’s easy to be cleaned out after used as the catalyst and without leaving any residue.

The tetramethylammonium hydroxide can be use as polarographic reagent to Precipitation the ash free hydride when we analysising.
