Metabolite Identification
Common NameMethylphosphate
DescriptionMethylphosphate, also known as monomethyl phosphate or MMP, belongs to the class of organic compounds known as monoalkyl phosphates. These are organic compounds containing a phosphate group that is linked to exactly one alkyl chain. Methylphosphate is a moderately acidic compound (based on its pKa). Methylphosphate is a methyl ester of phosphoric acid. It is a colourless, nonvolatile liquid, and it has some specialized uses in the production of other compounds.
