Monosodium phosphate

Molecular Formula: NaH₂PO₄
Molecular Weight: 119.959
CAS Number: 7558-80-7
Customs Code: 28352200
Alias: MSP

Characteristics:

  • Melting point: 60°C
  • Easily soluble in water, insoluble in ethanol
  • Below 100°C, it dissolves in crystalline water to form a monohydrate
  • At 100°C, it loses its crystalline water to become anhydrous; further heating converts it to sodium metaphosphate

Description

Product Uses:

  • Industrial Uses: Boiler water treatment, electroplating, leather tanning, detergents, fuel additives, dye auxiliaries, mica separation, acid buffers
  • Food and Fermentation Industries: Used as a quality improver and leavening agent in baking powder, and as a feed additive
  • Raw Material: Used in the production of sodium hexametaphosphate and tetrasodium pyrophosphate

Packaging, Storage, and Transportation:

  • Available in 25kg, 50kg, 1000kg, 1200kg, 1250kg bags with customizable options.
  • Store in a dry, well-ventilated area, and avoid exposure to moisture. It retains its quality during long-term storage, and any clumping can be resolved by crushing or dissolving before use.
  • Non-toxic and non-hazardous, it can be transported by road, sea, or rail as general cargo.
