Uses and Applications
- Food Processing: Used as a color retention agent and preservative in meat products, maintaining the bright red color of meat, inhibiting the growth of Clostridium botulinum, and extending the shelf life of food. Suitable for processing meat products such as sausages, ham, and cured meats.
- Industrial Corrosion Inhibition: As a highly effective corrosion inhibitor, it is used in industrial circulating water, boiler water, and passivation treatment after metal pickling. It forms a protective film on the metal surface, inhibiting corrosion and extending equipment lifespan.
- Chemical Synthesis: Used as an intermediate in the synthesis of dyes, pharmaceuticals, pesticides, and other products. It participates in the preparation of azo dyes, rubber antioxidants, and pharmaceutical intermediates, and is a key raw material in fine chemical production.
- Other Fields: Used in metal surface treatment (rust prevention, electroplating), and can also be used as a laboratory reagent, cement early strength agent, etc.
