Description
ARSENIC(V) OXIDE HYDRATE, also known as Arsenic pentoxide, is a white powdery chemical compound with the chemical formula As2O5·nH2O, where n represents the number of water molecules associated with the compound. It is an odorless, nonflammable solid that can exist in a lumpy or powdery form. Arsenic pentoxide is commonly shipped as a concentrated water solution due to its solubility in water.
Uses
Used in Chemical Industry:
ARSENIC(V) OXIDE HYDRATE is used as a precursor for the production of various arsenic compounds, such as arsenic trioxide and arsenic triiodide. These compounds find applications in the pharmaceutical, metallurgical, and electronics industries.
Used in Glass Manufacturing:
ARSENIC(V) OXIDE HYDRATE is used as a decolorizing agent in the glass industry. It helps to remove unwanted colors and impurities from the glass, resulting in a clearer and more transparent final product.
Used in Semiconductor Industry:
ARSENIC(V) OXIDE HYDRATE is used as a dopant in the semiconductor industry. It is added to silicon or other semiconductor materials to modify their electrical properties, enhancing their performance in electronic devices.
Used in Wood Preservation:
ARSENIC(V) OXIDE HYDRATE is used as a wood preservative, particularly in the treatment of marine pilings and other structures exposed to water. It helps to protect the wood from decay, rot, and insect damage.
Used in Pharmaceutical Industry:
ARSENIC(V) OXIDE HYDRATE is used in the pharmaceutical industry for the synthesis of various drugs, including those used in the treatment of certain types of cancer, such as acute promyelocytic leukemia.
Used in Pesticide Industry:
ARSENIC(V) OXIDE HYDRATE is used in the production of certain pesticides, particularly those used to control insect pests in agriculture.
Potential Exposure
Arsenic pentoxide is used in production
of metal arsenates; as an herbicide, defoliant on cotton;
as a chemical intermediate; as an ingredient in wood preservatives;
and in glass. Other possible uses are as an insecticide
and soil sterilant.
Shipping
UN1559 Arsenic pentoxide, Hazard Class: 6.1;
Labels: 6.1-Poisonous materials.
Incompatibilities
Decomposes above 315 C, forming oxygen
and arsenic trioxide fumes. Arsenic pentoxide is an
oxidizer; reacts violently with bromine pentafluoride and
reducing agents. The solution in water is a weak acid.
Incompatible with acids, strong alkalis; halogens, rubidium
carbide, zinc. Corrosive to metals in the presence of moisture.
Contact with acids or acid mists releases deadly arsine
gas.
Waste Disposal
Dissolve in a minimum of
concentrated hydrochloric acid. Dilute with water until
white precipitate forms. Add HCl to dissolve. Saturate with
H2S; filter and wash precipitate and return to supplier.
Alternatively, precipitate with heavy metals, such as lime
or ferric hydroxide in lieu of H2S. If needed, seek
professional environmental engineering assistance from
the United States Environmental Protection Agency
Environmental Response Team at (908) 548-8730 (24-hour
response line). Consult with environmental regulatory agencies
for guidance on acceptable disposal practices.
Generators of waste containing this contaminant (≥100 kg/
mo) must conform with EPA regulations governing storage,
transportation, treatment, and waste disposal. In accordance
with 40CFR165, follow recommendations for the disposal
of pesticides and pesticide containers. Must be disposed
properly by following package label directions or by contacting your local or federal environmental control
agency, or by contacting your regional EPA office.
Check Digit Verification of cas no
The CAS Registry Mumber 12044-50-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,4 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 12044-50:
(7*1)+(6*2)+(5*0)+(4*4)+(3*4)+(2*5)+(1*0)=57
57 % 10 = 7
So 12044-50-7 is a valid CAS Registry Number.
