Hypophosphorous Acid
Hypophosphorous acid (H3PO2) from Wuhan Silworld Chemical Co., Ltd. is supplied as a colorless to slightly yellow liquid with a minimum concentration of 50%. The compound carries CAS number 6303-21-5 and is fully miscible in water, making it a versatile reagent for industrial chemical processes. Trace impurities are tightly controlled, with iron capped at 0.005% and sodium at 1.0% max, ensuring consistency for downstream applications.
This grade of hypophosphorous acid serves primarily as a reducing agent in electroplating and electroless nickel plating, where its stability and reactivity are critical. It is also used in the synthesis of flame retardants and pharmaceuticals, where high purity and low impurity levels are standard requirements. Typical industrial grades of hypophosphorous acid are provided at 50% concentration, with iron and heavy metal content often controlled to parts per million levels for sensitive applications.
Industrial buyers of hypophosphorous acid include manufacturers in electronics, metal finishing, and specialty chemical production. The product is traded in bulk liquid drums or IBC containers, with logistics typically arranged under FOB or CIF terms. Buyers should confirm packaging compatibility with their handling systems, as the acid requires non-reactive containers to prevent degradation during transit.

Sourcing Hypophosphorous Acid from Wuhan Silworld Chemical Co., Ltd. - China Import Guide
Before ordering hypophosphorous acid from Wuhan Silworld Chemical Co., Ltd., verify the supplier’s current operational status and quality control certificates. Request a recent certificate of analysis (COA) to confirm the 50% concentration and impurity levels, as these directly impact performance in electroplating and chemical synthesis. Ensure the supplier can provide Material Safety Data Sheets (MSDS) compliant with your country’s regulations.
Confirm logistics details, including packaging type (drums or IBC containers) and compatibility with your handling systems. Lead times and Incoterms (e.g., FOB Wuhan) should be clarified, as bulk liquid shipments may require specialized transport. Payment terms such as L/C or T/T are typical for chemical imports but must be agreed upon in advance.
Quality checks should include testing for concentration, iron, sodium, and heavy metal content upon receipt. Inspection of packaging for leaks or contamination is standard for corrosive liquids. Documentation to verify includes the COA, MSDS, and any applicable industry certifications (e.g., ISO 9001 for quality management).
