Since the ends are condensed, its formula has one less H 2 O (water) than tripolyphosphoric acid. The general formula of a phosphoric acid is H n−2x+2 P n O 3n−x+1, where n is the number of phosphorus atoms and x is the number of fundamental cycles in the molecule's structure; that is, the minimum number of bonds that would have to be ...
Phosphate esters have the general structure P(=O)(OR) 3 feature P(V). Such species are of technological importance as flame retardant agents, and plasticizers. Lacking a P−C bond, these compounds are in the technical sense not organophosphorus compounds but esters of phosphoric acid. Many derivatives are found in nature, such as ...
These are primarily the esters of phosphoric acid and can be mono‑esters, di‑esters or tri‑esters depending on the number of attached organic groups (abbreviated as 'R' in the image below). In general man‑made organophosphates are most often triesters, while biological organophosphates are usually mono- or di-esters.
In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid, a.k.a. phosphoric acid H 3 PO 4. The phosphate or orthophosphate ion [PO 4] 3− is derived from phosphoric acid by the removal of three protons H +.
Alkyl phosphates belong to a group of organic compounds called organophosphates.They are esters of phosphoric acid H 3 PO 4 and corresponding alcohol.For example, the formula of methyl phosphate is CH 3-H 2 PO 4, dimethyl phosphate – (CH 3) 2 HPO 4 and trimethyl phosphate – (CH 3) 3 PO 4.
An ester of a carboxylic acid.R stands for any group (typically hydrogen or organyl) and R ′ stands for any organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (R ′).

General ester of phosphonic acid; in fact, the phosphorus has a formal charge of +1, the oxygen above it has a formal charge of −1, and the bond between them is single. In organic chemistry , phosphonates or phosphonic acids are organophosphorus compounds containing C−PO(OR) 2 groups , where R is an organic group ( alkyl , aryl ).
These acids, and their esters and salts ("phosphates") include some of the best-known and most important compounds of phosphorus. Orthophosphoric acid, H 3 PO 4. The simplest member of this class is: Phosphoric acid proper (also called orthophosphoric acid or monophosphoric acid), H 3 PO 4 (or OP(OH) 3), a triprotic acid.
