SHORT DESCRIPTION

Hexane Extra Pure is a high-purity, colorless liquid hydrocarbon known for its low boiling point and excellent solvency properties. It is extensively used in laboratories as a non-polar solvent for extractions, chromatography, and purification processes. Due to its volatility and ability to dissolve oils and fats, hexane is also employed in the preparation of samples for analysis, especially in organic chemistry and analytical laboratories. Its extra pure grade ensures minimal impurities, making it suitable for critical applications in pharmaceutical research, food testing, and industrial quality control.

Description

USES

Primary Laboratory Uses:

Non-polar solvent in organic extractions:
Widely used to extract oils, lipids, and other non-polar compounds from plant or animal materials in biochemical and organic chemistry labs.
Chromatographic solvent:
Commonly employed as the mobile phase in thin-layer chromatography (TLC) and column chromatography for separating non-polar analytes.

Secondary Laboratory Uses:

Cleaning and degreasing agent in analytical setups:
Utilized to remove oily residues or organic contaminants from laboratory glassware and instruments.
Volatile medium for recrystallization of hydrophobic compounds:
Used in purification protocols where controlled evaporation helps isolate non-polar substances.
Diluent for hydrophobic reagents or standards:
Acts as a carrier or diluting agent for certain laboratory standards in GC (gas chromatography) and preparative work.

SAFETY HANDLING PRECAUTIONS

SAFETY PRECAUTIONS

Personal Protective Equipment (PPE):

Wear a lab coat, chemical-resistant nitrile gloves, and protective goggles.
Use a properly functioning fume hood or respirator to avoid inhalation.

Handling:

Avoid contact with skin, eyes, and clothing.
Keep away from heat, sparks, open flames, and hot surfaces.
Avoid inhaling vapors and ensure good ventilation.
Ground and bond containers when transferring material.

Storage:

Store in a cool, dry, and well-ventilated area away from direct sunlight.
Keep the container tightly closed.
Store away from oxidizing agents, acids, and ignition sources.

FIRST AID MEASURES

Inhalation:

Move the person to fresh air immediately.
If breathing is difficult, provide oxygen and seek medical attention.
If not breathing, begin artificial respiration.

Skin Contact:

Remove contaminated clothing.
Wash affected areas with soap and water.
Seek medical attention if irritation develops.

Eye Contact:

Rinse cautiously with water for at least 15 minutes.
Remove contact lenses if present and easy to do.
Seek immediate medical attention.

Ingestion:

Do not induce vomiting.
Rinse your mouth thoroughly with water.
Seek immediate medical attention.

FIRE FIGHTING MEASURES

Flammability:

Highly flammable liquid and vapor.
Vapors may form explosive mixtures with air.

Extinguishing Media:

Use dry chemical, alcohol-resistant foam, carbon dioxide (CO₂), or water spray.
Do not use a direct water jet.

Hazardous Combustion Products:

May emit carbon monoxide and carbon dioxide upon combustion.

Firefighter Protection:

Wear full protective gear and a self-contained breathing apparatus (SCBA).
Cool containers with water spray to prevent pressure build-up and explosion.
