CAS Number: 2549-53-3
Concentration: 98-100%
Impurities: Trace stabilizers, inhibitors (such as MEHQ or hydroquinone monomethyl ether) below 500ppm if added, unspecified proprietary stabilizers sometimes included to extend shelf life and prevent polymerization.

4. First Aid Measures

Eye Contact: Rinse eyes very gently with clean water for a minimum of 15 minutes. Remove contact lenses if present and easy to do. Contact a doctor if irritation continues.
Skin Contact: Remove contaminated clothing. Wash skin thoroughly with soap and water. If redness or discomfort lasts, seek medical advice.
Inhalation: Move person to fresh air without delay. Keep them calm and warm. If symptoms like coughing or headache persist, medical evaluation is necessary.
Ingestion: Rinse mouth thoroughly. Never induce vomiting unless told by medical personnel. Seek immediate medical attention.

5. Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Unsuitable Extinguishing Media: Direct water jet may cause spread of fire
Hazardous Combustion Products: Acrid smoke, carbon monoxide, carbon dioxide, methyl acrylate fumes
Firefighting Instructions: Use standard protective equipment including self-contained breathing apparatus for fire personnel. Remove all possible containers from fire area if it is safe.
Other Information: Vapors form explosive mixtures with air; containers may explode when heated. Use water spray to cool unopened containers exposed to fire.

6. Accidental Release Measures

Personal Precautions: Evacuate unnecessary personnel, ventilate area, avoid inhalation of vapors. Wear chemical-resistant gloves, eye protection, and a suitable mask.
Environmental Precautions: Prevent run-off into drains, sewers, or waterways.
Methods for Cleaning Up: Absorb liquid spill with earth, sand, or inert absorbent material. Gather waste in suitable containers for regulated disposal. Clean contaminated area with soap and water if needed.
Additional Guidance: Isolate spill area until clean-up is complete.

7. Handling and Storage

Handling: Work in areas with good ventilation. Avoid direct contact with skin and eyes. No eating, drinking, or smoking while using the product. Use spark-proof tools and discharge static electricity safely.
Storage: Store in cool, dark, dry locations away from heat sources and sunlight. Keep container tightly sealed. Maintain storage temperature below 30°C. Keep away from strong oxidizers, acids, and bases. Drums or other packages should be properly labeled and inspected regularly for leaks or degradation.

8. Exposure Controls and Personal Protection

Exposure Limits: No specific occupational exposure limits for Bio-N-Heptyl Methacrylate available; recommended to keep exposure as low as possible.
Engineering Controls: Use local exhaust or general ventilation. Fume hoods for laboratory scale work; explosion-proof ventilators in industrial settings.
Personal Protective Equipment: Chemical splash goggles or safety glasses, gloves made from nitrile rubber or similar, long sleeves, and closed-toe shoes. Organic vapor respirators in cases of poor ventilation or high airborne concentration. Emergency showers and eyewash stations must be accessible.
