Uses

TAME is mostly used as an oxygenate to gasoline. It is added for three reasons: to increase octane enhancement, to replace banned tetraethyl lead, and to raise the oxygen content in gasoline. It is known that TAME in fuel reduces exhaust emissions of some volatile organic compounds.^[1]

Toxicity

When exposed to lab rats at 4000 ppm only 25% survived, the rats that died, died of central nervous system depression.^[3]
