High Purity Sodium Dihydrogen Arsenate with CAS 10048-95-0

Product Overview

Disodium hydrogen arsenate, molecular formula Na2HAsO4, is an orthorhombic crystal. Used as insecticides, preservatives, as well as research on agricultural resources. The substance is a human carcinogen. Animal experiments have shown that the substance may cause human reproductive or developmental toxicity. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Package sealed. Should be stored separately from oxidants, acids, and food chemicals. Avoid mixing. Storage area should be equipped with suitable materials for containment and leakage. Personal protective equipment: Particulate respirator adapted to the airborne concentration of the substance. Do not allow the chemical to enter the environment. Use professional equipment to aspirate or carefully clean the container. Carefully collect the residue and transfer to a safe place. Do not use a Household Vacuum Cleaner to aspirate this material. Use only professional equipment. According to the degree of exposure, it is recommended that medical examinations be performed regularly. Do not bring work clothes home.

Chemical dangers
Upon heating, the substance decomposes, producing toxic and corrosive fumes. Reacts with acid to generate toxic helium gas. In the presence of water, many metals (such as iron, aluminum, and zinc) are eroded to produce toxic arsenic and antimony fumes.
Contact route
The substance can be absorbed into the body through inhalation of its aerosol and ingested into the body.
Inhalation risk
When dispersed, especially powder, harmful concentrations of airborne particles can be reached quickly.
Impact of short-term exposure
The substance irritates the eyes and respiratory tract. The substance may have effects on the gastrointestinal tract, leading to severe gastroenteritis, loss of body fluids and electrolytes, heart disease and shock. Contacting well above the occupational exposure limit may result in death. Impact may be delayed. Need medical observation.
Effects of long-term or repeated exposure
The substance may have effects on the skin, mucous membranes, peripheral nervous system, bone marrow, and liver, leading to pigmentation, hyperkeratosis, nasal perforation, neuropathy, anemia, and liver damage. The substance is a human carcinogen. Animal experiments have shown that the substance may cause human reproductive or developmental toxicity.
