| Gefahrenübersicht | An irritantToxic by ingestion and inhalation[Alfa Aesar MSDS] Almost nothing is known regarding health effects of organic arsenic compounds in humans. Studies in animals show that some simple organic arsenic compounds are less toxic than inorganic forms. Ingestion of methyl and dimethyl compounds can cause diarrhea and damage to the kidneys.

Anwendungen & Verwendung
Beschreibung
Triphenylarsin bildet farblose, wasserunlösliche, trikline Tafeln. Es ist leicht löslich in Diethylether und Benzol. Die Substanz ist zu 5 % im sogenannten Arsinöl enthalten, welches im 1. Weltkrieg als chemischer Kampfstoff verwendet wurde.
Verwenden
Triphenylarsine is used in certain metal-catalyzed coupling reactions. It is a precursor to tetraphenylarsonium chloride a popular precipitating agent.
