Applications/Uses

Antioxidant and stabilizer: It can be added to pharmaceutical formulations to help maintain stability and extend shelf life.

Other Major Applications

1. Electroless Nickel Plating

One of the important industrial applications of sodium hypophosphite is as a reducing agent in electroless nickel-plating processes.

It participates in the chemical reduction process that enables nickel deposition without requiring the conventional external electrical current used in electroplating. Sodium hypophosphite is documented as a reducing agent for electroless nickel plating on metals and plastics. 

Typical industries include:

• Engineering components

• Automotive components

• Metal finishing

• Machinery parts

• Electronic components

• Precision components

• Surface-treatment industries

2. Chemical Processing

Sodium hypophosphite can be used as a reducing reagent and chemical intermediate in specialty chemical manufacturing and laboratory processes. 

3. Surface Treatment

Its reducing characteristics make sodium hypophosphite useful in selected surface-treatment and metal-finishing formulations, particularly those associated with electroless deposition processes.

4. Laboratory & Research Applications

Sodium hypophosphite is used as a chemical reagent in laboratory and analytical applications where its reducing properties are required. 

5. Specialty Chemical Manufacturing

The material can serve as a raw material or process reagent in selected specialty chemical formulations and manufacturing processes.

Physical Appearance

RXSOL Sodium Hypophosphite is generally supplied as a white, odourless crystalline or granular solid. Sodium hypophosphite monohydrate is described by PubChem as a white hygroscopic/deliquescent crystalline material. 

Because the material can absorb moisture, appropriate moisture-protected packaging and storage are recommended.

Solubility

Sodium hypophosphite is water soluble, making it convenient for preparation of aqueous process solutions where required.

The exact solubility profile can vary with temperature, grade and whether the product is supplied in anhydrous or hydrated form.

Grades & Specifications

RXSOL Sodium Hypophosphite can be offered according to customer requirements, including suitable industrial or specialty grades.

Typical specification parameters may include:

• Assay

• Moisture / loss on drying

• pH of solution

• Insoluble matter

• Phosphite content

• Phosphate content

• Heavy metals

• Iron

• Calcium

• Other trace impurities

Final specifications should always be confirmed from the current RXSOL TDS and batch COA.

Chemical Identification

For the monohydrate form, the CAS number is 10039-56-2 and PubChem reports a molecular weight of approximately 103.98 g/mol. Therefore, the exact CAS and molecular weight should be matched to the grade supplied.
