SHORT DESCRIPTION

Aluminium Chloride Hydrated Extra Pure is a high-purity, white to pale yellow crystalline compound containing bound water molecules, making it less reactive than its anhydrous counterpart but still highly effective in various laboratory applications. It is commonly used in aqueous-phase reactions, coordination chemistry, and as a reagent for studying aluminum ion behavior in solution. The hydrated form offers enhanced stability and ease of handling, making it suitable for educational experiments, buffer formulations, and inorganic synthesis where precise aluminum content is required. Its extra pure grade ensures minimal interference from impurities, supporting accurate and reproducible results in analytical and research settings. Proper storage in a cool, dry place is essential to prevent further hydration or contamination.

SAFETY HANDLING PRECAUTIONS

SAFETY PRECAUTIONS

  1. Personal Protective Equipment (PPE): 
    • Use chemical-resistant gloves (e.g., nitrile), lab coat, safety goggles, and optionally a face shield for bulk handling. 
    • Work in a well-ventilated lab or under a chemical fume hood.

    • Remove contaminated clothing and clean before reuse. 
    • Avoid eating, drinking, or smoking in the laboratory. 

FIRST AID MEASURES 

  1. Inhalation: 
    • Move the exposed person to fresh air. 
    • If symptoms like coughing, throat irritation, or difficulty breathing occur, seek medical attention. 
    • Provide oxygen if breathing is difficult. 
  2. Skin Contact: 
    • Remove contaminated clothing. 
    • Rinse skin thoroughly with soap and water. 
    • Seek medical attention if irritation or chemical burns develop.

    • Seek immediate medical attention—corrosive to eyes. 
  4. Ingestion: 
    • Rinse your mouth thoroughly with water. 
    • Do not induce vomiting. 
    • If the person is conscious, give water or milk to dilute. 
    • Seek immediate medical help, as the compound may be corrosive internally. 

FIRE FIGHTING MEASURES

  1. Suitable Extinguishing Media: 
    • Use dry chemicals, carbon dioxide (COâ‚‚), or foam. 
    • Use water spray only to cool containers—not directly on the chemical. 
  2. Specific Hazards: 
    • Not flammable, but may decompose at high temperatures, releasing hydrogen chloride gas (HCl) and irritating fumes. 
    • Reacts with strong bases and oxidizers, potentially causing exothermic reactions.

    • Wear full protective gear and a self-contained breathing apparatus (SCBA). 
  4. Firefighting Instructions: 
    • Keep exposed containers cool using water spray. 
    • Avoid inhalation of vapors or decomposition fumes. 
    • Isolate the area and ventilate if safe to do so.
