What is Ethylamine?
Ethylamine (CAS 75-04-7) is a primary aliphatic amine; FEMA 4236.
Where is Ethylamine used?
- Pharmaceutical synthesis: building block for active ingredients
- API synthesis: neutralizing agent
- Polymer processing: curing and cross-linking agent in resin systems, including flame-retardant formulations where nitrogen content contributes to char-forming mechanisms
- Food flavoring: approved flavoring agent contributing characteristic notes in processed food systems
- Specialty chemicals: stabilizer and pH buffer
- Controlled basicity is required during production.
Good to know: Pharmaceutical-grade material meets USP and BP specifications; technical-grade product serves industrial polymer and chemical synthesis applications.
Commercial specifications
- Aqueous solutions typically at 70% concentration
- Packaging: cylinders and ISO tanks for anhydrous material; drums and IBCs for aqueous grades
