CAS No. 1493-13-6 is an organic compound widely used in the chemical industry. It is an aqueous solution of sodium hypophosphite with a molecular formula of NaH2PO2. This compound has a wide range of applications such as reducing agent, metal cleaning agent, corrosion inhibitor, antifreeze, dyeing and bleaching agent, etc.

As a reducing agent, sodium hypophosphite can reduce metal oxides, sulfides and even organic compounds to their corresponding metals, which can be used in metallurgical processes such as electroplating, pickling and soldering. In addition, it can be used as a metal cleaner because it can dissolve rust and other dirt on the metal surface, thus making the metal surface bright and clean. As a corrosion inhibitor, sodium hypophosphite can effectively protect metals from corrosion by forming a protective film on the metal surface. As an antifreeze, it can lower the freezing point of water and protect from freezing damage. In the dyeing and bleaching industry, it can be used as a bleaching agent to whiten and brighten colored fabrics.

The purity of sodium hypophosphite is usually in the range of 90-98%. It is a colorless and odorless aqueous solution with a pH value of 8.6-10. The solubility of sodium hypophosphite in water is more than 80%. It is stable under normal temperature and pressure, but it can decompose at higher temperature.

CAS No. 1493-13-6 is a widely used organic compound in the chemical industry. Its applications are very diverse and can be used in various industries. It is essential to correctly handle and store this organic compound in order to ensure its safety and quality.
