Bicyclic phosphate

Bicyclic phosphate is a class of organophosphate compounds that are used as flame retardants, stabilizers and antioxidants. They are also used in spectroscopic studies.[1][2]

Some bicyclic phosphates, such as TBPS, TBPO and IPTBO, are highly toxic. They have toxicity comparable to nerve agents. However, they are not acetylcholinesterase inhibitors.[1] They act as GABA receptor antagonists and have potent convulsant effects.[2][3][4]
