High-purity sodium hypophosphite monohydrate (NaH₂PO₂·H₂O) with ≥99.0% assay by titration.
Low heavy metal content (<5 ppm total heavy metals), ensuring suitability for electroless nickel plating baths.
Excellent solubility in water (>60 g/100 mL at 25°C) and stable crystalline structure under standard storage conditions.
Consistent batch-to-batch performance validated through rigorous QC testing per ISO 9001 protocols.
Non-hygroscopic granular form with controlled particle size distribution for precise dosing and minimal dust generation.
Primary reducing agent in electroless nickel-phosphorus (Ni-P) plating solutions for aerospace and automotive components.
Stabilizer and co-reducing agent in copper electroless deposition processes for printed circuit board (PCB) manufacturing.
Phosphorus source in flame-retardant formulations for engineering plastics and polymeric composites.
Chemical intermediate in the synthesis of phosphinic acid derivatives and specialty catalysts.
Reducing agent in pharmaceutical fine chemical synthesis requiring mild, selective reduction conditions.
