Deliquescent solid; [Merck Index] Powder; [Alfa Aesar MSDS]

Sources/Uses

Occurs naturally in plants and animals; Used in the treatment of homocystinuria; [Merck Index] Used in soldering and resin curing fluxes, in organic synthesis, and in fisheries (promotes fish survival and aids transfer of salmon and trout from freshwater to seawater); [HSDB] "Trimethylglycine (TMG) is an organic compound that occurs in plants. Trimethylglycine was the first betaine discovered; originally it was simply called betaine because, in the 19th century, it was discovered in sugar beets. Since then, many other betaines have been discovered, and the more specific name glycine betaine distinguishes this one." [Wikipedia]
