Trimethyl phosphite appears as a clear colorless liquid with a strong foul odor. Flash point 99 °F. Denser than water and insoluble in water. Vapors heavier than air. Used to make other chemicals. Trimethyl phosphite is an organophosphorus compound that is phosphane in which the three hydrogens are replaced by methoxy groups.

用作制磷胺、敌敌畏、灭蚜净、久效磷等农药的中间体。 由亚磷酸三苯酯与甲醇在甲醇钠的催化剂存在下，进行酯交换而制得。 在空气中易挥发，并易氧化成磷酸三甲酯。 遇水分解成亚磷酸二甲酯，遇酸立即水解。 对一般金属无明显腐蚀作用。
