Frequently Asked Questions

What is urea phosphate used for?

Urea phosphate (CAS 4861-19-2) is the crystalline 1:1 adduct of urea and phosphoric acid, delivering both nitrogen and phosphorus in one acidic compound. Its documented use is as a plant fertilizer and soil amendment, including in aqueous (liquid) fertilizer applications and as an acidifying soil amendment.

How is urea phosphate produced?

Urea phosphate is produced by reacting urea with phosphoric acid to form the 1:1 crystalline adduct (CH7N2O5P). The reaction combines the nitrogen of urea and the phosphorus of phosphoric acid into a single acidic, water-soluble compound.

Is urea phosphate water soluble?

Yes. Urea phosphate is a water-soluble crystalline compound, which is why it is used in aqueous liquid-feed fertilizer systems and fertigation. It also lowers solution pH due to its acidic character. Consult the SDS for full physical-property data.

What is the chemical formula and CAS number of urea phosphate?

The molecular formula is CH7N2O5P and the CAS number is 4861-19-2. It is the urea-phosphoric acid adduct supplying both nitrogen and phosphorus nutrients.

How is urea phosphate supplied in bulk and what is the cost?

Urea phosphate is typically supplied as a crystalline or granular fertilizer-grade solid in bags or bulk. Pricing depends on grade, volume, packaging, and lead time, so request a bulk quote from RawSource rather than relying on spot listings; CoA and SDS are provided per lot.
