Useful:

• Chemical Classes: Metals -> Arsenic Compounds, Inorganic
• Drug Classes: Trace Elements and Metals
• Canonical SMILES: [As]
• Recent ClinicalTrials: A Study Comparing the Effects and Safety of Dulaglutide With Glimepiride in Type 2 Diabetes Mellitus
• Recent NIPH Clinical Trials: Post remission therapy including arsenic trioxide against acute promylocytic leukemia (APL) in elderly patients. (JALSG APL212G study)
• Inhalation Risk: A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered.
• Effects of Short Term Exposure: The substance may cause effects on the gastrointestinal tract. This may result in severe gastroenteritis, loss of fluids and electrolytes, cardiac disorders, shock and convulsions. Exposure far above the OEL could cause death. The effects may be delayed. Medical observation is indicated.
• Effects of Long Term Exposure: The substance may have effects on the skin, mucous membranes, peripheral nervous system, liver and bone marrow. This may result in pigmentation disorders, hyperkeratosis, perforation of the nasal septum, neuropathy, anaemia and liver impairment. This substance is carcinogenic to humans. Animal tests show that this substance possibly causes toxicity to human reproduction or development.

Technology Process of Arsenic

There total 6 articles about Arsenic which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

arsenic + hydrogen (1333-74-0) → arsenic (7440-38-2,460345-38-4,7784-42-1,127323-69-7) + arsenic hydride (12628-08-9,7784-42-1,127323-69-7) + AsH2 (14644-45-2,7784-42-1,127323-69-7) + diarsine (88934-46-7,88934-45-6,15942-63-9)
