Catalog reference cue; confirm supplier documentation before use.

Handling & PPE

  • Handle in a well-ventilated area or fume hood.
  • Avoid inhalation, ingestion, and skin/eye contact.
  • Keep container tightly closed in a dry, cool, and well-ventilated place.
  • Store away from incompatible materials.
  • Use appropriate PPE such as lab coat, compatible gloves, and eye protection.
  • Wear respiratory protection if ventilation is inadequate or if dust/aerosol is generated.
  • Ensure emergency eye wash stations and safety showers are available.
  • Dispose through approved chemical waste channels.
  • Follow all local and institutional regulations for chemical waste.

First Aid / Accidental Release

  • In case of inhalation, move to fresh air.
  • For skin contact, rinse cautiously with water.
  • For eye contact, rinse cautiously with water for several minutes.
  • If swallowed, rinse mouth. Do NOT induce vomiting.
  • Seek medical attention according to institutional procedures if irritation or symptoms persist.
  • For spills, avoid dust or aerosol generation.
  • Collect spilled material using trained-lab procedures.
  • Ensure adequate ventilation during cleanup.
  • Wear appropriate personal protective equipment.

Firefighting / Stability

  • Use extinguishing media appropriate for the surrounding fire.
  • Wear self-contained breathing apparatus and full protective gear.
  • Keep containers cool with water spray if involved in fire.
  • Avoid inhalation of hazardous combustion products.
  • Considered stable under recommended storage conditions.
  • Avoid strong oxidizing agents and strong acids/bases.
  • May react with incompatible materials.
  • No specific hazardous reactions are known under normal research-use conditions.
