Arsphenoxide Specification

Arsphenoxide (CAS NO.538-03-4) is also named as 2-Amino-4-arsenosophenol hydrochloride ; 3-Amino-4-hydroxy-phenarsine hydrochloride ; 3-Amino-4-hydroxyphenyl arsinoxide hydrochloride ; 3-Amino-4-hydroxyphenylarsine oxide hydrochloride ; AI3-04455 ; Arseno 39 ; Arsenosan ; Arsenoxide ; Ehrlich 5 ; Fontarsan ; Mapharsal ; Mapharsen ; Mapharside ; Metarsen ; NSC 3087 ; Oxiarsolan ; Oxophenarsine HCl ; Oxophenarsine hydrochloride ; Oxophenarsini hydrochloridum ; Treparsen . Arsphenoxide (CAS NO.538-03-4) is highly toxic. It is flammable. It will produce toxic nitrogen oxides, arsenic and hydrogen chloride fumes when buring. So the storage environment should be ventilate, low-temperature and dry. Keep Arsphenoxide (CAS NO.538-03-4) separate from raw materials of food.
