Applications
Laboratory and analytical solvent (ACS reagent): extraction, chromatography and spectroscopy.Adjudicated
Restrictions on Use: For industrial, professional and laboratory use. Do not use for cleaning or degreasing in poorly ventilated spaces: repeated n-hexane exposure damages the peripheral nerves.
Storage & Handling
- Recommended Storage
- Keep containers tightly closed in a cool, dry, well-ventilated flammables area away from heat, sparks, open flame and direct sunlight. Ground and bond containers when transferring. Protect from light.Adjudicated
- Handling Precautions
- Eliminate ignition sources. Use chemical-resistant nitrile or PVA gloves. Bond and ground all transfer equipment. Vapors heavier than air — control ventilation accordingly.Class-level guidance — not product-specific; the SDS controls.
- Incompatibilities
- Strong oxidizing agents; halogens (chlorine, fluorine) and halogen compounds.Adjudicated
- Shelf Life
- Consult Technical Services for product-specific shelf life
For full hazard, PPE, and emergency response guidance, refer to the Safety Data Sheet (SDS) for this product. The SDS controls in all cases where guidance differs.
