Based on QSAR modeling and read-across vinyl neononanoate will be very resistant to UV light degradation and hydrolysis. Vinyl neononanoate's hydrolysis half-life at ph 7 was estimated to be 273 to > 2900 days.

Based on experimental data for the structural analog, vinyl neodecanoate in O.E.C.D. Testing Guideline studies for biodegradation, vinyl neononanoate is anticipated to not be readily or inherently biodegradable. The maximum biodegradation achieved for vinyl neodecanoate in ready biodegradation O. E. C. D. guideline studies was 14 - 17% at 28 days of contact.

Based on findings for the structural anaog, vinyl neodecanoate, in an O.E.C.D. 305 Testing Guideline 305 fish feeding study, vinyl neononanoate is anticipated to have a Bioconcentration Factor of 1100 - 1400.

Based on O.E.C.D. Toolbox QSAR modeling vinyl neononanoate is predicited to demonstrate moderate adsorption to organic material and slow migratiion potential to groundwater. Read-across to MacKay Fugacity modeling data for the structural analog vinyl neodecanoate suggest that approximately 100% of the vinyl neononanoate released to the atmosphere will remain in the the air compartment. If released to water bodies, MacKay Fugacity modeling suggest that approximately 99% of vinyl neononaoate will remain in the water/sediment compartment.
