Trimethyl Phosphonoacetate CAS 5927-18-4

Trimethyl Phosphonoacetate is a colourless transparent liquid. Mainly used as intermediates in the synthesis of organophosphorus compounds (e.g. pesticides, flame retardants), lithium additives and metal extractants, and its phosphate ester structure gives high reactivity and flame retardancy. It needs to be sealed and kept away from light, it is irritating to skin and eyes, protection is needed when operating.
