Arsenic trioxide is an inorganic compound with the formula As 2 O 3. [5] As an industrial chemical, its major uses include the manufacture of wood preservatives ...
Arsenic trioxide powder.. Compounds of arsenic resemble in some respects those of phosphorus which occupies the same group (column) of the periodic table.The most common oxidation states for arsenic are: −3 in the arsenides, which are alloy-like intermetallic compounds, +3 in the arsenites, and +5 in the arsenates and most organoarsenic compounds.
A trihalide in chemistry is an organohalide consisting of three halide atoms bonded to a single atom or compound. [1] [2] An example of a trihalide is chloroform. The trihalomethanes are the simplest trihalides, because only one hydrogen is connected to the carbon. The 1,1,1-Trichloroethane is one of the trihalides of ethane.
Arsenic is a chemical element with the symbol As and the atomic number 33. It is a metalloid and one of the pnictogens, and therefore shares many properties with its ...
Arsenic trichloride can be prepared by the reaction of arsenic oxide and sulfur monochloride. This method requires simple apparatus and proceeds efficiently: [8] 2 As 2 O 3 + 6 S 2 Cl 2 → 4 AsCl 3 + 3 SO 2 + 9 S. A convenient laboratory method is refluxing arsenic(III) oxide with thionyl chloride: [9] 2 As 2 O 3 + 3 SOCl 2 → 2 AsCl 3 + 3 SO 2
Later, on similar routes, the corresponding and isostructural arsenic and antimony species were also synthesized. [3] Other synthetic methods involve deprotonation of OH or NH groups in the presence of ECl 3 (E=P, [ 4 ] As, Sb [ 5 ] and Bi [ 6 ] ), salt metathesis [ 7 ] or reduction of pentavalent pnictogen compounds.
Arsenic trioxide, even at low concentrations, causes the degradation of PML/RARα, thereby partially restoring the differentiation of cancerous promyelocytes. [31] Arsenic trioxide activates JNK (c-Jun N-terminal kinase), also known as stress-activated protein kinase, which belongs to the MAPK (mitogen-activated protein kinase) family. These ...
