Applications – Phosphorus pentoxide is a versatile compound and used in wide range of applications:
Organic synthesis | It can be used as a reagent for condensations in organic synthesis and polymerisation reactions. Typical uses include cyclisation / ring closures in such reactions as acetylation, alkylation, production of amines, acid amides, cyclic ketones, cyclic olefins or oxygen and sulphur heterocyclic compounds. |
Catalyst production | It can be used in the manufacture of special phosphoric acid supported catalysts. |
Specialty inorganic phosphates | Phosphorus pentoxide can be used in the manufacture of specialty sodium and ammonium phosphates. |
Polyphosphoric acids | Various grades of superphosphoric and polyphosphoric acids can be manufactured by blending phosphorus pentoxide with phosphoric acid. |
Glass | Beside silicon dioxide and boron trioxide also phosphorus pentoxide is used for glass making. |
Phosphate esters | It can be used to produce phosphate esters with a mono/di ester content. The acid is reacted directly with the appropriate alcohol or phenol to produce the acidic phosphate ester. |
Drying agent | Because of its strong hygroscopic properties phosphorus pentoxide can be used as a drying agent. |
Fertilizers | In production of ammonium polyphosphate. |
Surfactants | In manufacture of cetyloleyl ether phosphoric acid, cetylstearyl ether phosphoric acid, nonylphenol ether phosphoric acid. |

L-Phenylalanine (L-Phe) is an essential and proteinogenic amino acid that helps build proteins and produces brain chemicals like dopamine and norepinephrine. L-Phenylalanine is one of the 20 standard amino acids that form long chains called polypeptides (proteins).The body cannot produce it, so it must be obtained through diet or supplements.
L-carnitine Hydrochloride is a water soluble, stable salt form of L- Carnitine. It is a naturally occurring amino acid derivative. It is often used as a dietary supplement due to its role in energy production and fat metabolism.
Dimenhydrinate is an antihistamine drug commonly used to prevent and treat motion sickness, nausea, and vertigo. It is a combination of diphenhydramine and 8-chlorotheophylline, where the latter reduces the sedative effects of diphenhydramine. It is available in tablet, liquid, and injectable forms under various brand names.
o-Nitrophenyl Disulfide is a chemical compound used in organic chemistry and biochemistry. It is a disulfide derivative where two o-nitrophenyl groups are connected by a disulfide bond (-S-S-) It is used in various organic synthesis reactions, as a reagent in the preparation of thiol-reactive compounds, in pharmaceutical research and laboratory applications.
Tetrasodium pyrophosphate (TSPP) anhydrous is a white, crystalline or granular inorganic compound, soluble in water but insoluble in alcohol. TSPP is widely used in food, industrial, and cleaning applications due to its sequestrant, dispersing, buffering, and emulsifying properties.
