502-39-6 Usage
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

Check Digit Verification of cas no
The CAS Registry Mumber 502-39-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,0 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 502-39:
(5*5)+(4*0)+(3*2)+(2*3)+(1*9)=46
46 % 10 = 6
So 502-39-6 is a valid CAS Registry Number.
