CAS Number
106-93-4Synonym
EDB; Ethylene dibromide; Ethylene bromide
Occurrence/Use
Pesticide for felled logs and beehives; chemical intermediate for dyes, resins, waxes, and gums. Former pesticide and ingredient of soil and grain fumigant formulations until these uses were banned in the US in 1984. Use as a lead scavenger in antiknock gasoline mixtures ended with the phase-out of leaded gasoline in the US by 1996. Trace amounts occur naturally in the ocean.
