Sodium cacodylate 97+ Usage And Synthesis

Chemical Properties

White crystalline powder

Chemical Properties

Sodium cacodylate is a white crystalline solid which occurs as the trihydrate. It liquefies in the water of hydration @ 60°C and becomes anhydrous @ 120°C.

Uses

Herbicide.

Definition

ChEBI: The organic sodium salt of dimethylarsinate.

General Description

A white crystalline or granular solid with a slight odor. Toxic by ingestion, inhalation, and skin absorption. Used as a herbicide.

Air & Water Reactions

Soluble in water.

Reactivity Profile

Sodium cacodylate 97+ gives basic solutions in water. Corrodes common metals, but reaction is not hazardous. [USCG, 1999]. Liquefies in its own water of crystallization when heated to 60°C; becomes anhydrous at 120°C [Merck]. Burns with a bluish flame, emitting a garlic-like odor [Merck].

Hazard

Toxic by inhalation and ingestion.

Health Hazard

Moderately toxic; probable oral lethal dose in humans is 0.5-5 g/kg or between 1 ounce and 1 pint (or 1 lb.) for a 70 kg (150 lb.) person. It may cause disturbances of the blood, kidneys, and nervous system.

Fire Hazard

Poisoning potential is high when heated to decomposition, or on contact with acids or acid fumes, because Sodium cacodylate 97+ emits highly toxic fumes of arsenic. Avoid water solution in contact with active metals (iron, aluminum, zinc).

Agricultural Uses

Herbicide, Rodenticide, Defoliant, Veterinary medicine: This material has been used as a non-selective herbicide and defoliant for general weed control. Severely restricted for use in EU countries. Not registered for use in the U.S. There are 47 global suppliers

Potential Exposure

This material has been used as a nonselective herbicide and for general weed control.

Shipping

UN1688 Sodium cacodylate Hazard Class: 6.1; Labels: 6.1-Poisonous materials. UN3465 Organoarsenic compound, solid, n.o.s., Hazard Class: 6.1; Labels: 6.1Poisonous materials, Technical Name Required

Purification Methods

Recrystallise it from aqueous EtOH. [Beilstein 4 H I 612.]

Incompatibilities

Incompatible with oxidizers, strong bases; acids, active metals (iron, aluminum, zinc). Contact with acids react to form highly toxic dimethylarsine gas. Attacks some metals.

Waste Disposal

For cacodylic acid, precipitate as calcium arsenate and calcium arsenite by treatment with excess lime water. Recycle if possible. If not, put in secure storage for possible disposal in leach-proof dumps. 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.
