Phosphate and Phosphorous
1. Ammonium Dihydrogen Phosphate
CAS No.: 7722-76-1
Ammonium Dihydrogen Phosphate (ADP) or Monoammonium Phosphate, NH4H2PO4, is formed when a solution of phosphoric acid is added to ammonia until the solution is distinctly acidic. It crystallizes in tetragonal prisms. Monoammonium phosphate is often used in the blending of dry agricultural fertilizers. It supplies soil with the elementsnitrogen and phosphorus in a form which is usable by plants. The compound is also a component of the ABC powder in some dry chemical fire extinguishers. This substance is also supplied in an emerald green or aquamarine crystal growing box kit for children.
2. Disodium Phosphate
CAS No.: 7558-79-4
Disodium Phosphate (Na2HPO4) is a sodium salt of phosphoric acid. It is a white powder that is highly hygroscopic and water soluble. It is therefore used commercially as an anti-caking additive in powdered products. It is also known as disodium hydrogen orthophosphate, sodium hydrogen phosphate or sodium phosphate dibasic. It is commercially available in both the hydrated and anhydrous forms. pH of disodium hydrogen phosphate water solution is between 8.0 and 11.0.
3. Diammonium Phosphate
CAS No.: 7783-28-0
DAP is used as a fertilizer. When applied as plant food, it temporarily increases the soilpH, but over a long term the treated ground becomes more acidic than before upon nitrification of the ammonium. It is incompatible with alkaline chemicals because its ammonium ion is more likely to convert to ammonia in a high-pH environment. The average pH in solution is 7.5 - 8. The typical formulation is 18-46-0 NPK
4. Monosodium Phosphate
CAS No.: 7558-80-7
Monosodium Phosphate (NaH2PO4), also known as anhydrous monobasic sodium phosphate and sodium dihydrogen phosphate, is a chemical compound of sodium with aphosphate counterion. It is used as a laxative and, in combination with other sodium phosphates, as a pH buffer.
5. Monopotassium Phosphate
CAS No.: 7778-77-0
Monopotassium Phosphate (also potassium dihydrogen phosphate, KDP, ormonobasic potassium phosphate, MKP) -- KH2PO4 -- is a soluble salt which is used as a fertilizer, a food additive and a fungicide. It is a source of phosphorus and potassium. It is also a buffering agent. When used in fertilizer mixtures with urea and ammonium phosphates, it minimizes escape of ammonia by keeping the pH at a relatively low level.
6. Sodium Triphosphate
CAS No.: 7758-29-4
Sodium Triphosphate (STP, sometimes STPP or sodium tripolyphosphate or TPP) is an inorganic compound with formula Na5P3O10. It is the sodium salt of the polyphosphatepenta-anion, which is the conjugate base of triphosphoric acid. It is produced on a large scale as a component of many domestic and industrial products, especially detergents. Environmental problems associated with eutrophication are attributed to its widespread.
7. Sodium Hexametaphosphate
CAS No.: 10124-56-8
SHMP Sodium Hexametaphosphateis used as a sequestrant and has applications within a wide variety of industries, including as a food additive in which it is used under the E number E452i. Sodium carbonate is sometimes added to SHMP to raise the pH to 8.0-8.6, which produces a number of SHMP products used for water softening and detergents. Also used as a dispersing agent to break down clay and other soil types.
8. Sodium Triphosphate
CAS No.: 7758-29-4
Sodium Triphosphate (STP, sometimes STPP or sodium tripolyphosphate or TPP) is an inorganic compound with formula Na5P3O10. It is the sodium salt of the polyphosphatepenta-anion, which is the conjugate base of triphosphoric acid. It is produced on a large scale as a component of many domestic and industrial products, especially detergents. Environmental problems associated with eutrophication are attributed to its widespread.
9. Trisodium Phosphate
CAS No.: 7601-54-9
10. Tetra Sodium Pyrophosphate
CAS No.: 13472-36-1

I just wanted to take this time to say thanks for the continued great service… you still out-perform (the competition) in service and pricing.
I think the team [does] good work. To be honest I don’t know what can be better...good feedback, timely, fast quotation, fast delivery, I think it is a good company with a good product.
