WebPhosphonates or phosphonic acids are organic compounds containing C–PO (OH)2 or C–PO (OR) 2 groups (where R = alkyl, aryl). Most phosphonates are highly water soluble, while the phosphonic acids are only sparingly soluble. Phosphonates are not volatile and are poorly soluble in organic solvents.
