1、Chemical Name: Urea Phosphate
2、Molecular Formula: H3PO4·CO(NH2)2
3、Molecular Weight: 158.056
4、CAS: 4861-19-2
5、Character: It’s white granular crystal，easily soluble in water, insoluble in organic solvent. Melting point is 117.3℃, the aqueous solution is strong acidity, the pH of 1% aqueous solution is 1.89. It is easily decomposed when heated because of the low heat stability.
6、Usage:It can be used as feed ingredient which can provide the element phosphorus and non protein nitrogen, it is more safe than UREA. It is a kind of high concentration nitrogen and phosphorus compound fertilizer(total nutrition assay is 62%), it is apply to the alkaline soil. It can be used as fire retardant, metal surface ingredient, fermentation nutrient, detergent and purification agent of phosphorus.
7、Packing: It is packed with polyethylene bag as inner layer, and a compound plastic woven bag as outer layer. The net weight of each bag is 25kg.
8、Storage & Transportation: It should be stored in a dry and ventilative warehouse, kept away from heat
and moisture during transportation, unloaded with care so as to avoid damage. Furthermore, it must be
stored separately from poisonous substances.
