| Hazard Information | Back Directory | [Chemical Properties]
tricl crystal(s); when dry, decomposes on standing to form a yellow crust on the surface; spontaneously decomposed at 43°C–49°C; used to treat dermatitis and jaundice caused by arsphenamine [MER06] | [Purification Methods]
Recrystallise it from water below 60o in a N2 atmosphere, followed by drying with EtOH and Et2O. Store it in a refrigerator. The hexahydrate can decompose spontaneously at 43-49o. Store it in a cool closed container. [Pethybridge & Taba J Chem Soc, Faraday Trans 1 78 1331 1982.] |
