7784-46-5 Usage

Description

Sodium m-arsenite, also known as Sodium arsenite, is an inorganic sodium salt with the chemical formula NaAsO2. It appears as a white or grayish-white powder or flakes and is denser than water. Contact with Sodium m-arsenite may irritate the skin, eyes, and mucous membranes, and it can be toxic through ingestion, inhalation, and skin absorption.

Uses

Used in Pest Control Industry:
Sodium m-arsenite is used as an insecticide, particularly for termites, and in the manufacture of arsenical soap for use on skins. It is also utilized for treating vines against certain scale diseases.
Used in Hide and Skin Preservation:
In the leather industry, Sodium m-arsenite serves as a hide preservative, helping to prevent decay and deterioration.
Used in Pharmaceutical and Chemical Industries:
Sodium m-arsenite is employed as an antiseptic due to its properties that help prevent the growth of microorganisms. Additionally, it is used in the production of dyes and soaps, contributing to their effectiveness and quality.
Used in Stressor Applications:
Sodium m-arsenite is used as a stressor to induce the production of heat shock proteins, which are essential for cellular protection and response to various stressors.

Air & Water Reactions

Soluble in water. Slowly converted in solution to arsenates by atmospheric oxygen; in dry state Sodium m-arsenite is decomposed by carbon dioxide. [EPA, 1998].

Reactivity Profile

Salts, basic, such as SODIUM ARSENITE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.

Hazard

Toxic by ingestion and inhalation.

Health Hazard

Extremely toxic: probable oral lethal dose (human) 5-50 mg/kg, between 7 drops and one teaspoon for 70 kg person (150 lb.). Poisonous if swallowed or inhaled. Human suspected carcinogen.

Fire Hazard

Sodium m-arsenite may burn but does not ignite readily. When heated Sodium m-arsenite emits toxic fumes of arsenic and sodium oxide. Slowly converted in solution to arsenates by atmospheric oxygen; in dry state Sodium m-arsenite is decomposed by carbon dioxide.

Safety Profile

Confirmed human carcinogen. Human poison by ingestion. Experimental poison by ingestion, skin contact, intravenous, intramuscular, and intraperitoneal routes. An experimental teratogen. Experimental reproductive effects. Human mutation data reported. Used as an herbicide and pesticide. When heated to decomposition it emits toxic fumes of arsenic and NazO. See also ARSENIC COMPOUNDS.

Potential Exposure

This material is used in manufacturing of arsenical soap for use on skin; treating vines against certain scale diseases; wood preservation; as a reagent in preparation of Methylene iodide; corrosion inhibitor; and for herbicidal and pesticidal purposes

Shipping

UN2027 Sodium arsenite, solid, Hazard Class: 6.1; Labels: 6.1-Poisonous materials. UN1686 Sodium arsenite, aqueous solutions, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.

Incompatibilities

Chemically active metals. Arsine, a very deadly gas, can be released in the presence of acid, acid mists, or hydrogen gas.

Waste Disposal

The arsenic may be precipitated as calcium arsenite. It should be stored until recycled. 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 7784-46-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 4 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7784-46:
(6*7)+(5*7)+(4*8)+(3*4)+(2*4)+(1*6)=135
135 % 10 = 5
So 7784-46-5 is a valid CAS Registry Number.
InChI:InChI=1/AsO2.Na/c2-1-3;/q-1;+1
