Trimethylolethane (TME) is the organic compound with the formula CH₃C(CH₂OH)₃. This colorless solid is a triol, as it contains three hydroxy functional groups. More specifically, it features three primary alcohol groups in a compact neopentyl structure. Its esters are known for their resistance to heat, light, hydrolysis, and oxidation. More important than TME and closely related is trimethylolpropane (TMP).
