ChEBI: 2,2-dimethylpropanoic acid [[1-[bis[(2,2-dimethyl-1-oxopropoxy)methoxy]phosphoryl]-1-(4-hydroxyphenoxy)ethyl]-[(2,2-dimethyl-1-oxopropoxy)methoxy]phosphoryl]oxymethyl ester is an organooxygen compound and a pivalate ester. It is functionally related to a tetracarboxylic acid.

Cell-permeable prodrug of the potent inositol monophosphatase inhibitor L-690,330 ([1-(4-Hydroxyphenoxy)ethylidene]bisphosphonic acid ); penetrates cells more effectively than its metabolite.
