| Application: | Ammonium phosphate dibasic can be used as a catalyst: • To synthesize tetrahydrobenzo[b]pyranderivatives via three‐component condensation reaction. • In the solvent-free Biginelli reactions. • To synthesize bis(indolyl)methanes via solvent-free reaction of indole derivatives and aromatic or aliphatic aldehydes. |
| General description: | Ammonium phosphate dibasic is a water-soluble ammonium phosphate salt. It is a key component of phosphate fertilizers. It is commonly used as a flame retardant for plywood, paper, and fabrics, as well as a corrosion inhibitor consolidant for degraded carbonatic materials found in old buildings. |
