What is potassium salt of phosphonic acid?
Potassium Salt of Phosphonic Acid is primarily a water-soluble fungicide, It is effective in controlling diseases caused by a group of fungi known as the oomycetes (Phytophthora, Plasmopara, Pythium, and others).
What is Aminotrimethylene phosphonic acid?
Acid – amino trimethylene phosphonic acid (ATMP) ATMP is added in various chemical formulations for industrial water treatment, oilfield, industrial cleaners, paper & pulp, textile industry, metal treatment, electroplating, inks & construction chemicals as a scale inhibitor and a complexing agent.
What is phosphite fertilizer?
Phosphite ( ; Phi), a reduced form of phosphate ( ; Pi), is widely marketed as either a fungicide or fertilizer or sometimes as a biostimulant.
How is phosphite made?
The most common phosphite is potassium phosphite, and is made by mixing a solution of potassium hydroxide with phosphonic acid. Potassium phosphite is also referred to as mono- and di-potassium salts of phosphorous acid on some phosphonate product labels.
What is sodium diethylenetriamine pentamethylene phosphonate?
Use: Diethylenetriamine penta(methylene phosphonic acid) sodium salt (DTPMPA Na) is a cost effective scale inhibitor used in various industrial applications such as industrial water treatment and detergents.
What is the full form of ATMP?
Companies can consult the European Medicines Agency (EMA) to determine whether a medicine they are developing is an advanced therapy medicinal product (ATMP). The procedure allows them to receive confirmation that a medicine, which is based on genes, cells or tissues, meets the scientific criteria for defining an ATMP.
How do you make phosphite?
Is phosphonic acid organic?
Phosphonates 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.
How is phosphoric acid made?
Phosphoric acid, H3PO4, is produced from phosphate rock by wet process or thermal process. 80% of the world’s phosphoric acid is obtained by the wet process. The wet process consists of reaction, filtration and concentration steps. The phosphate rock is ground and acidified with sulfuric acid in the reactor vessel.
Is siRNA an ATMP?
Neither FDA nor EMA consider siRNAs to be gene therapy. “FDA regulates them as a drug, not a biologic, and they are not an ATMP,” explained Meffen; siRNA therapies do not have RMAT status.
Is phosphonate soluble in water?
Phosphonates or phosphonic acids are organophosphorus compounds containing C−PO (OH) 2 or C−PO (OR) 2 groups (where R = alkyl, aryl ). Phosphonic acids, typically handled as salts, are generally nonvolatile solids that are poorly soluble in organic solvents, but soluble in water and common alcohols.
What is the difference between phosphonate salts and esters?
Phosphonate salts are the result of deprotonation of phosphonic acids, which are diprotic acids: Phosphonate esters are the result of condensation of phosphonic acids with alcohols. Several methods exist for the preparation of phosphonic acids and their salts.
What are phosphonic acids?
Phosphonic acids, typically handled as salts, are generally nonvolatile solids that are poorly soluble in organic solvents, but soluble in water and common alcohols. Many commercially important compounds are phosphonates, including glyphosate (the active molecule of the herbicide “Roundup”), and ethephon, a widely used plant growth regulator.
Why are phosphonates used as chelating agents?
The demand of phosphonates grows steadily at 3% annually. Since the work of Gerold Schwarzenbach in 1949, phosphonic acids are known as effective chelating agents. The introduction of an amine group into the molecule to obtain −NH 2 −C−PO (OH) 2 increases the metal binding abilities of the phosphonate.
