The general structure of a phosphite ester showing the lone pairs on the P. In organic chemistry, a phosphite ester or organophosphite usually refers to an organophosphorous compound with the formula P(OR) 3. They can be considered as esters of an unobserved tautomer phosphorous acid, H 3 PO 3, with the simplest example being trimethylphosphite ...
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.
It also reduces discoloration (yellowing) of plastics. The compound is a phosphite ester formed by the reaction of 2,4-di-tert-butylphenol with phosphorus trichloride. [1] It is an approved food contact materials in the US. [2]
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).
Triethyl phosphite (TEP) is an organophosphorus compound, specifically a phosphite ester, with the formula P(OCH 2 CH 3) 3, often abbreviated P(OEt) 3. It is a colorless, malodorous liquid. It is used as a ligand in organometallic chemistry and as a reagent in organic synthesis.
Any −OH groups on the phosphates in these ester molecules may lose H + ions to form anions, again depending on the pH in a solution. In the biochemistry of living organisms, there are many kinds of (mono)phosphate, diphosphate, and triphosphate compounds (essentially esters ), many of which play a significant role in metabolism such as ...
General ester of phosphonous acid Not to be confused with phosphinite (formula P(OR)R 2 ). In organic chemistry , phosphonites are organophosphorus compounds with the formula P(OR) 2 R.
Food plot in Germany. A food plot is a planted area set aside to act as a supplementary food source for wildlife. The term was coined by the U.S. hunting and outdoor industries and food plots are most commonly planted for game species. Food plot crops generally consist of but are not limited to legumes (clovers, alfalfa, beans, etc.), grains ...
