Description: 

• Axít hypophosphorous (HPA), hoặc axit phosphinic, là một oxyacid phốt pho và là chất khử mạnh với công thức phân tử H₃PO₂
• Là một hợp chất nóng chảy thấp không màu, có thể hòa tan trong nước, dioxan và rượu.
• HPA có nhiều tác dụng như:
  – Reducing agent.
  – Antioxidants.
  – Catalysts.
  – Color stabilizers.
  – Surfactant.

Standards: 

• Hypophosphorous acid concentration: 50 – 52%
• pH: 1.4
