Flammability code 2: Must be moderately heated or exposed to relatively high ambient temperature before ignition can occur. Flash point between 38 and 93 °C (100 and 200 °F). E.g. diesel fuelHealth code 3: Short exposure could cause serious temporary or residual injury. E.g. chlorine gasReactivity code 3: Capable of detonation or explosive decomposition but requires a strong initiating source, must be heated under confinement before initiation, reacts explosively with water, or will detonate if severely shocked. E.g. hydrogen peroxideSpecial hazards (white): no code

Tetraethyltin is a colourless flammable liquid, soluble in diethyl ether and insoluble in water, that freezes at -112 °C and boils at 181 °C.[1][2] It is used in the electronics industry.

Tetraethyltin can be obtained by reacting ethylmagnesium bromide with tin(IV) chloride:[1]

SnCl4 + 4 (C2H5)MgBr → (CH3CH2)4Sn + 4 MgBrCl

The same reaction can be used to obtain tetra-n-propyltin and tetra-n-butyltin.[1]

Tetraethyltin is converted in the body to the more toxic triethyltin.[3]
