Reported in EPA TSCA Inventory.
Mildly toxic by ingestion and inhalation. A skin and eye irritant. Upon absorption by the body it can hydrolyze to acetic acid and isobutanol. Highly flammable liquid. A very dangerous fire and moderate explosion hazard when exposed to heat, flame, or oxidizers. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and fumes. See also Esters and n-butyl acetate.

Isobutyl acetate , with CAS number of 110-19-0, can be called Aceticacid, isobutyl ester ; 2-Methylpropyl acetate ; Isobutyl acetate ; b-Methylpropyl ethanoate . Isobutyl acetate Like many esters, it has a fruity or floral smell at low concentrations and occurs naturally in raspberries, pears and other plants. At higher concentrations the odor can be unpleasant and may cause symptoms of central nervous system depression such as nausea, dizziness and headache. The chemical compound Isobutyl acetate (CAS NO.110-19-0)) is a common solvent. It is produced from the esterification of isobutanol with acetic acid, can be used as a solvent for lacquer and nitrocellulose.
