(1-hydroxyheptane-1,1-diyl)bis(phosphonic acid)

(1-Hydroxyheptane-1,1-diyl)bis(phosphonic acid) is a synthetic small molecule belonging to the bisphosphonate class of compounds. It contains two phosphonate groups attached to a heptane backbone and is structurally related to other bisphosphonates used in medicine for bone disorders. Its primary mechanism of action is inhibition of farnesyl pyrophosphate synthase—an enzyme critical in the mevalonate pathway—which disrupts osteoclast-mediated bone resorption. This compound has not been approved for medical use and remains experimental; it has no known clinical indications or completed clinical trials as of June 2025[2][7]. It may be studied as a research tool or specialty chemical.
