DescriptionECHEMI Editorial ReferenceWhite, slightly deliquescent crystals or granules. The USP 32 states that monobasic sodium phosphate contains one or two molecules of water of hydration or is anhydrous.
The hydrated forms of monobasic sodium phosphate occur as odorless, colorless or white, slightly deliquescent crystals. The anhydrous form occurs as a white crystalline powder or granules.
