Arsenic is a common n-type dopant in semiconductor electronic devices. It is also a component of the III–V compound semiconductor gallium arsenide. Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. These applications are declining with the ...
Arsenic trioxide is indicated in combination with tretinoin for treatment of adults with newly-diagnosed low-risk acute promyelocytic leukemia whose acute promyelocytic leukemia is characterized by the presence of the t(15;17) translocation or PML/RAR-alpha gene expression; and for induction of remission and consolidation in patients with acute promyelocytic leukemia who are refractory to, or ...
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 ...
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.
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.
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.

Inorganic arsenic and its compounds, upon entering the food chain, are progressively metabolized to a less toxic form of arsenic through a process of methylation. [7] Organoarsenic compounds arise via biomethylation of inorganic arsenic compounds, [ 8 ] via processes mediated by enzymes related to vitamin B 12 . [ 9 ]
