General chemical structure of the organophosphate functional group. In organic chemistry, organophosphates (also known as phosphate esters, or OPEs) are a class of organophosphorus compounds with the general structure O=P(OR) 3, a central phosphate molecule with alkyl or aromatic substituents. [1]
See the general structure image of an ortho- (or mono-) phosphate ester below on the left, where any of the R groups can be a hydrogen or an organic radical. Di- and tripoly- (or tri-) phosphate esters, etc. are also possible.
Tris(2,4-di-tert-butylphenyl)phosphite is an organophosphorus compound with the formula [(C 4 H 9) 2 C 6 H 3 O] 3 P. This white solid is a widely used stabilizer in polymers where it functions as a secondary antioxidant.
It is a phosphate ester-based fluid that is known for its excellent fire resistance and ability to withstand extreme temperature and pressure conditions. It is manufactured by Solutia (now part of Eastman Chemical Company), and formerly manufactured by Monsanto. There are various lines of Skydrol including Skydrol 500B-4, Skydrol LD-4, and ...

Purple acid phosphatases (PAPs) (EC 3.1.3.2) are metalloenzymes that hydrolyse phosphate esters and anhydrides under acidic condition. [1] [2] In their oxidised form, PAPs in solution are purple in colour. This is due to the presence of a dinuclear iron centre, [3] to which a tyrosine residue is connected via a charge transfer. [4]
Trixylyl phosphate (TXP) is an aromatic phosphate ester. It was historically used as a flame retardant for acetate plastics (cellulose nitrate and cellulose acetate) and PVC. It also saw significant use as a fire-resistant hydraulic fluid. Trixylyl phosphate is now banned or restricted in several jurisdictions, due to its poor safety profile.
Triethyl phosphate is an organic chemical compound with the formula (C 2 H 5) 3 PO 4 or OP(OEt) 3. It is a colorless liquid. It is a colorless liquid. It is the triester of ethanol and phosphoric acid and can be called "phosphoric acid, triethyl ester".
