  • Boiling Point: Approximately 137 °C (at 760 mmHg)
  • Density: Around 1.023 g/mL at 25 °C
  • Flash Point: Approximately 41 °C (This indicates it is a flammable liquid, requiring appropriate precautions).
  • Solubility: Soluble in water (partly), and miscible with many organic solvents.

Safe Handling Practices
Due to its flammable nature and potential irritant properties, proper handling of Methyl 2-hydroxyisobutyrate is essential. Always:

  • Work in a Well-Ventilated Area: Use fume hoods or ensure adequate local exhaust ventilation.
  • Avoid Ignition Sources: Keep away from heat, sparks, open flames, and hot surfaces. No smoking.
  • Wear Personal Protective Equipment (PPE): This includes chemical-resistant gloves (e.g., nitrile or neoprene), safety glasses or goggles, and protective clothing.
  • Prevent Skin and Eye Contact: In case of contact, rinse immediately with plenty of water. Seek medical attention if irritation persists.
  • Ground and Bond Containers: When transferring the liquid, to prevent static discharge.

Optimal Storage Conditions
To maintain the quality and stability of Methyl 2-hydroxyisobutyrate, proper storage is crucial:

  • Container: Store in tightly closed containers, preferably the original packaging.
  • Temperature: Recommended storage is at room temperature or in a cool, dry place. Some sources suggest storage at 2-8°C, particularly for long-term preservation of high purity.
  • Environment: Keep away from incompatible materials such as strong oxidizing agents and strong acids/bases.
  • Location: Store in a cool, well-ventilated area, segregated from flammable materials.
