What is Ethyl bromide?
Ethyl bromide (CAS 74-96-4), also known as bromic ether, is a low-boiling alkylating and brominating agent.
Where is Ethyl bromide used?
- Pharmaceutical manufacturing: key intermediate for N- or O-ethylation reactions
- Agrochemicals: preparation of herbicide and pesticide intermediates
- Plastics and polymers: flame retardant formulations
- Textile and leather processing: solvent carrier in specialty treatment baths
- It serves as an ethylating agent where controlled carbon-chain extension is required.
Good to know: Buyers should confirm purity thresholds and stabilizer content with suppliers, as these vary by the intended downstream application.
Commercial specifications
- Liquid in drums and ISO tank containers
- Quantities from laboratory to bulk industrial volumes
- High-purity grades meet pharmaceutical intermediate specifications
