Product Details

Product Introduction:

Product Name:Monosodium Phosphate Dihydrate (Technical Grade)

English Name:MSP.2H₂O Monosodium Phosphate Dihydrate (Technical Grade)

Molecular Formula:NaH₂PO₄·2H₂O

CAS No.:13472-35-0

Executive Standard:HG/T 2767-2009

Physical and Chemical Properties:

Appearance:White granular crystals

Molecular Weight:156.01

Density:1.915 g/cm³
