Hydrazine Food Grade

Whatsapp Order

Hydrazine Food Grade is a high-purity form of hydrazine (N₂H₄), a highly reactive, colorless, and fuming liquid with a pungent ammonia-like odor. It is a powerful reducing agent and chemical intermediate widely used in industrial applications. The food-grade specification ensures purity and controlled impurity levels suitable for limited and specialized food industry uses, primarily as a processing aid or sterilizing agent. Hydrazine exhibits strong nucleophilic and reducing properties, enabling various chemical transformations and sterilization processes.

Description

Hydrazine Food Grade

Primary Uses 

  1. Food Industry
  • Utilized as a processing aid in the manufacture of food additives such as azodicarbonamide, which acts as a flour bleaching and dough conditioning agent in baked goods.
  • Employed in food packaging production processes where it serves as a chemical intermediate for polymer synthesis.
  • Used in sterilization and sanitization of food processing equipment and water treatment, ensuring microbial control without residual toxicity when used properly.
  • Applied in fumigation and microbial control in food storage facilities under strict regulatory guidelines.
  1. Pharmaceutical and Chemical Industry
  • Functions as a chemical intermediate in the synthesis of pharmaceuticals, agrochemicals, and polymer resins used indirectly in food-contact materials.
  • Acts as a reducing agent in various chemical syntheses integral to producing food-grade ingredients.
  1. Water Treatment
  • Used as an oxygen scavenger in boiler feedwater and cooling systems within food processing plants to prevent corrosion and microbial growth.

 

Secondary Uses 

  1. Laboratory and Analytical Chemistry
  • Utilized in analytical procedures for detecting certain metals and compounds in food samples.
  1. Biochemical Research
  • Applied as a reagent in enzyme assays and biochemical studies relevant to food science.

  • Hygiene Practices: Immediate washing if contact occurs; thorough decontamination after handling

 

  1. First Aid Measures
  • Inhalation: Move victim to fresh air immediately; administer oxygen if breathing is difficult; seek emergency medical care promptly
  • Skin Contact: Remove contaminated clothing; rinse skin with plenty of water for at least 15 minutes; seek immediate medical attention
  • Eye Contact: Rinse eyes thoroughly with water for at least 15 minutes; urgent medical evaluation required
  • Ingestion: Do NOT induce vomiting; rinse mouth and seek immediate emergency medical assistance

 

  1. Firefighting Measures
  • Fire Hazards: Flammable and may form explosive mixtures with air; releases toxic nitrogen oxides and ammonia when burning
  • Extinguishing Media: Use dry chemical, foam, or carbon dioxide; avoid water jets as they may spread the fire
  • Special Precautions: Firefighters must wear full protective gear and self-contained breathing apparatus
  • Combustion Products: Toxic gases including nitrogen oxides and ammonia
