Glyphosate, part of the herbicide "Roundup", is a phosphonate. 2-aminoethylphosphonic acid: the first identified natural phosphonate. Phosphonates are one of the three sources of phosphate intake in biological cells. [citation needed] The other two are inorganic phosphate and organophosphates.
With the formula (HO) 2 P(O)CH 2 NHCH 2 CO 2 H, this derivative of glycine is one of the most widely used herbicides. Bisphosphonates are a class of drugs to treat osteoporosis. The nerve gas agent sarin, containing both C–P and F–P bonds, is a phosphonate. [citation needed] Phosphinates feature two P–C bonds, with the general formula R 2 ...
Organophosphate flame retardants are part of a wider family of phosphorus-based agents which include organic phosphonate and phosphinate esters, in addition to inorganic salts. [ 56 ] [ 57 ] When some prominent brominated flame retardant were banned in the early 2000s phosphorus-based agents were promoted as safer replacements.
Glyphosate is a derivative of aminophosphonic acid and the amino acid glycine. Both the phosphonic acid and carboxylic acid moieties can ionised (deprotonated) and the amine group can be protonated. Consequently the substance exists as a series of rapidly interchanging zwitterions.
3 (phosphonate) groups covalently linked to carbon determine both the name "bisphosphonate" and the function of the drugs. Bis refers to the fact that there are two such groups in the molecule. The long side-chain (R 2 in the diagram) determines the chemical properties, the mode of action and the strength of bisphosphonate drugs.

Oxime compounds can reactivate acetylcholinesterase by attaching to phosphorus, forming an oxime-phosphonate, which then splits away from the acetylcholinesterase molecule. Oxime nerve-agent antidotes are pralidoxime (also known as 2-PAM ), obidoxime , methoxime, HI-6 , Hlo-7, and TMB-4 . [ 24 ]
