Methanol Extra Pure

Whatsapp Order

Methanol Extra Pure is a clear, colorless, and highly volatile liquid with a mild alcohol-like odor, refined to an exceptional level of purity. It is widely used as a solvent in laboratories and industrial settings due to its excellent miscibility with water and many organic compounds. Methanol serves as a key reagent in chemical synthesis, particularly in the production of formaldehyde, methyl esters, and biodiesel. In analytical chemistry, it’s used for chromatography and spectroscopic applications where high purity is essential. Its rapid evaporation rate and strong solvency make it ideal for cleaning delicate equipment and preparing lab samples.

SAFETY HANDLING PRECAUTIONS

SAFETY PRECAUTIONS

Personal Protective Equipment (PPE):

Wear lab coats, chemical-resistant gloves (e.g., nitrile), and safety goggles.
Use in a fume hood or well-ventilated area.

Handling:

Avoid inhalation, ingestion, and contact with skin or eyes.
Do not use near open flames, sparks, or hot surfaces.
Wash thoroughly after handling.

Storage:

Store in a cool, dry, and well-ventilated area.
Keep the container tightly closed and away from heat, flames, and oxidizers.
Store in flammable liquid storage cabinets.

FIRST AID MEASURES

Inhalation:

Move the person to fresh air immediately.
If breathing is difficult, give oxygen and seek emergency medical help.

Skin Contact:

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

Eye Contact:

Rinse cautiously with plenty of 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 — methanol is toxic if ingested.

FIRE FIGHTING MEASURES

Flammability:

Highly flammable liquid and vapor.

Extinguishing Media:

Use alcohol-resistant foam, dry chemical, or carbon dioxide (CO₂).
Water spray can be used to cool exposed containers.

Hazardous Combustion Products:

May emit carbon monoxide (CO) and carbon dioxide (CO₂) when burned.

Firefighter Protection:

Wear self-contained breathing apparatus (SCBA) and full protective clothing.
