Physicochemical muaj:

Qhov khoom muaj tus ntxhiab tsw muaj Ammonia, nws yog ib qho alkaline thiab yooj yim rau assorb tus CO2, muaj ua rau cov tshuaj uas muaj water(Acohol). Cov tetramethylammonium hydroxide 5 siv lead ua dej yog acicular siv lead ua tsis muaj kob thiab diliquescence. Melting kis yog 63℃. Qhov kub taw tes yog 120℃。 Nws yuav decomposite trimethylamine thiab methanol thaum cua sov rau biling. Yog tus ceev cov khoom muag hauv 1.00(25/4℃), thiab nws yog ib tug alkali mater uas muaj zog corrosive. Txhob cia tus foob packing. Nws yog ib qho yooj yim moisure haum las pa. Decomposition kis yog 134℃. Peb hu nws "ib ntus catalyst lawm" ntawm nws lub qho yooj yim uas yuav ntxuav tom qab siv raws li cov catalyst thiab tsis tau tawm hauv tej residue.

Cov tetramethylammonium hydroxide yuav muab siv ua polarographic reagent rau cov ntoo av tshauv dawb hydride nag lossis daus thaum peb analysising.
