Description
This substance is an obsolete carbamate fungicide. Very little data relating to its environmental fate, ecotoxicity or impact on human health is available.
Chemical Properties
Pure white, colorless crystals. Melting point: 72.5-72.8°C. The original drug is an orange-yellow or light yellow aqueous solution, slightly alkaline, with an ammonia and hydrogen sulfide odor. It is readily soluble in water, slightly soluble in ethanol and acetone, and insoluble in benzene. It is unstable in air, while its aqueous solution is relatively stable, but it decomposes easily at temperatures above 40°C and in the presence of acidic substances.
Uses
Amobam is a fungicidal compound which is used to protect and treat vegetation. Pesticide.
Definition
ChEBI: A dithiocarbamate salt resulting from the formal reaction of ethylenebis(dithiocarbamic acid) with 2 mol eq. of ammonia. A water-soluble crystalline solid, it is a fungicide used to protect fruit, vegetable, and field crops against a wide spectrum of funga
diseases. Mixing amobam with zinc sulfate affords the fungicide zineb.
Production Methods
Diammonium ethylenebis(dithiocarbamate) would have been produced using the same industrial chemistry applied to other EBDC fungicides such as maneb, zineb, and nabam. Commercial manufacture began with ethylene diamine, which was reacted with carbon disulphide under alkaline conditions to form the ethylenebis(dithiocarbamate) anion. Neutralisation with ammonium salts yielded the diammonium form rather than the metal complexed EBDCs used more widely in agriculture.
Mechanism of action
Non-specific, inhibts respiration.
Safety Profile
Poison by ingestion. When heatedto decomposition it emits very toxic fumes of SOx andNOx.
