• Basic Information
  • Molecular Formula: C3​H6​BrNO4​
  • Molecular Weight: 199.988
  • CAS Registry Number: 52 - 51 - 7
  • Appearance: White to pale yellow or yellow - brown crystalline powder at room temperature.
  • Melting Point: About 130℃
  • Density: 1.2 g/cm³
  • Solubility: It is highly soluble in water, ethanol, and propylene glycol, and hardly soluble in chloroform, acetone, benzene, etc. The solubility in water is 250 g/L at 22℃.
• Physical and Chemical Properties
  • It is odorless and tasteless, with a vapor pressure of 1.68×10 kPa at 25ºC. It will slowly decompose in alkaline aqueous solutions, has a corrosive effect on metals such as aluminum, and will react with strong oxidants, strong alkalis, and strong acids. There is no risk of polymerization.
• Bactericidal Principle
  • The bromine atom can oxidize the thiol groups on the surface of the bacterial cell membrane, causing the cell wall to break and the intracellular substances to flow out, thus killing the bacteria. At the same time, the activated bromine released can combine with the proteins of the cell membrane, interfering with the cell metabolism and causing the death of bacteria. In addition, the formaldehyde released during its decomposition can also make the bacterial proteins coagulate, playing a bactericidal role.
• Application Fields
  • It is mainly used as a preservative and bactericide, widely used in cosmetics, detergents, fabric treatment agents, etc. It can also be used for the sterilization, mildew - proof, anti - corrosion, and algaecide in industrial circulating water, paper pulp, coatings, plastics, wood, etc. In addition, it can be used as a pesticide bactericide to prevent and control a variety of plant - pathogenic bacteria, such as the cotton black arm disease caused by the cotton angular spot pathogen.
• Reference Quality Index
  • Appearance: White crystalline particles.
  • Content: ≥99.0%
  • Moisture: ≤0.5%
• Toxicity and Safety
  • It is toxic and irritating to the eyes, skin, and mucous membranes, and can cause congenital abnormalities. The acute oral LD50 of rats is 180 - 400 mg/kg, and it is highly toxic to aquatic organisms.
• Packaging and Storage
  • It is usually packaged in a plastic barrel and sealed. Metal containers should be avoided. It should be stored in a cool, dry, and ventilated place, and should be strictly prohibited from being mixed with strong oxidants, strong alkalis, strong acids, and food during packaging, storage, and transportation.
