1-cyano-3-(methylmercurio)guanidine Chemical Properties,Usage,Production

Description

Methylmercuric dicyanamide is a crystallinesolid. Molecular weight = 298.72; Freezing/Meltingpoint 5 156℃. Hazard Identification (based on NFPA-704M Rating System): Health 3, Flammability 1, Reactivity 0.Soluble in water.

Chemical Properties

Methylmercuric dicyanamide is a crystalline solid.

General Description

Crystals. Used as a fungicide; a seed, soil, and turf treatment, especially for cereals, sorghum, sugar beets, cotton, and flax. Not registered as a pesticide in the U.S.

Reactivity Profile

1-cyano-3-(methylmercurio)guanidine is incompatible with strong oxidizing agents such as chlorine .

Health Hazard

1-cyano-3-(methylmercurio)guanidine is extremely toxic to humans. The probable lethal dose for humans is 5-50 mg/kg of body weight (between 7 drops and one teaspoon for a 150 lb. person). Humans may be poisoned by feeding on the flesh of animals which have ingested this fungicide. Eating treated seeds may also cause poisoning. The poisoning may show delayed manifestations on the nervous system. Patients frequently become gradually worse after their illness is recognized and exposure is stopped. 1-cyano-3-(methylmercurio)guanidine is a strong skin irritant and produces blisters and other dermatitis.

Fire Hazard

(Non-Specific -- Mercury-Based Pesticide, n.o.s.) 1-cyano-3-(methylmercurio)guanidine may burn but does not ignite readily. Container may explode in heat of fire. Fire and runoff from fire control water may produce irritating or poisonous gases. When heated to decomposition, 1-cyano-3-(methylmercurio)guanidine emits very toxic fumes of mercury and nitrogen oxides.

Safety Profile

Poison by ingestion and intraperitoneal routes. An experimental teratogen. Experimental reproductive effects. Mutation data reported. When heated to decomposition it emits very toxic fumes of Hg and NOx.

Potential Exposure

This material is used as a fungicide; a seed, soil, and turf treatment especially for cereals, sorghum, sugar beets, cotton, and flax. Not registered for use as a pesticide in the United States

First aid

If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit. Keepvictim quiet and maintain normal body temperature. Effectsmay be delayed; keep victim under observation.

storage

Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with thischemical you should be trained on its proper handling andstorage. Store in tightly closed containers in a cool, wellventilated area.

Shipping

UN2777 Mercury based pesticides, solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.

Incompatibilities

A strong reducing agent. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides

Waste Disposal

In accordance with 40CFR 165 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
