Isopropyl Alcohol CAS 67-63-0

Product Overview

Isopropyl Alcohol, also known as 2-Propanol or IPA, is a versatile, colorless, volatile liquid with a sharp, musty odor reminiscent of rubbing alcohol. It serves as an essential solvent and disinfectant in various industrial, pharmaceutical, and consumer applications. With its fast-evaporating properties and high solvency power, Isopropyl Alcohol CAS 67-63-0 is widely used for cleaning, extraction, and sterilization processes. Available in high-purity grades, it meets stringent standards for laboratory, manufacturing, and medical use.

Safety and Handling Information

Isopropyl Alcohol is classified as a hazardous substance due to its flammability and potential health effects. Key safety guidelines include:

  • Hazards: Highly flammable liquid and vapor (H225). Causes serious eye irritation (H319). May cause drowsiness or dizziness (H336).
  • First Aid: In case of eye contact, rinse with water for 15 minutes. For inhalation, move to fresh air. Seek medical attention if symptoms persist.
  • Storage: Store in a cool, well-ventilated area away from ignition sources. Keep containers tightly closed.
  • Personal Protective Equipment (PPE): Wear chemical-resistant gloves, safety goggles, and protective clothing. Use in well-ventilated spaces.
  • Environmental Considerations: Dispose of in accordance with local regulations; avoid release into waterways.

Always refer to the Safety Data Sheet (SDS) for detailed handling protocols.

Frequently Asked Questions (FAQs)

What is Isopropyl Alcohol CAS 67-63-0 used for?

Isopropyl Alcohol is a multi-functional solvent and disinfectant. It is commonly applied in cleaning electronics, as a rubbing alcohol for skin disinfection, in pharmaceutical preparations, and for industrial degreasing.

Is Isopropyl Alcohol safe for skin contact?

In diluted forms (e.g., 70% solution), it is safe for topical use as a disinfectant. However, undiluted IPA can dry and irritate skin. Always patch-test and follow dilution guidelines.

How should I store Isopropyl Alcohol to prevent hazards?

Store in a flammable liquids cabinet at temperatures below 27°C (80°F), away from heat, sparks, and open flames. Ensure proper ventilation to avoid vapor buildup.

What is the difference between Isopropyl Alcohol and Ethyl Alcohol?

Isopropyl Alcohol (IPA) is derived from propylene and is more effective as a solvent for non-polar substances, while Ethyl Alcohol (ethanol) is food-grade and better for beverages or higher-proof sanitizers. IPA evaporates faster.

Can Isopropyl Alcohol be used in food preparation?

No, it is not food-grade. Use denatured or grain alcohol for food-related applications. IPA is strictly for industrial, medical, and cleaning purposes.

What purity levels are available for Isopropyl Alcohol?

Standard grades include 99%+ for laboratory use, 70% for disinfectants, and technical grades for industrial cleaning. Contact us for specific requirements.

Does Isopropyl Alcohol expire?

It has a shelf life of 2-3 years when stored properly. Check for cloudiness or off-odors before use.
