Reported physical properties

How this substance is indexed

Documented uses

• A component (5%) of NIAX Catalyst ESN, along with dimethylaminopropionitrile (95%); used in the past as a catalyst in the manufacture of flexible polyurethane foams; [NIOSH]
• See Appendix C in NIOSH Pocket Guide. The neurotoxicity was apparently due to DMAPN (dimethylaminopropionitrile). See NIOSHTIC Record # 57566. CIB 26 published by NIOSH & OSHA in 1978.
• DMAEE is used primarily as a catalyst in the manufacturing of polyurethane foams.
• Propellants, non-motive (blowing agents)
