Isopropyl Alcohol is also called 2-Propanol, or IPA for short. It is a colorless, transparent liquid with a slight ethanol odor. It is miscible with water, ethanol, ether, and chloroform. Its vapor forms an explosive mixture with air, which can cause combustion and explosion when exposed to open flames or high heat. It can react violently with oxidants. If exposed to high heat, the pressure inside the container increases, and there is a risk of cracking and explosion. Its CAS number is 67-63-0, EINECS number is 200-661-7, chemical formula is C₃H₈O, and molecular weight is 60.1.

As an important organic compound, Isopropyl Alcohol has important uses:
- Medical field: 2-Propanol has a bactericidal effect. Its 70% - 75% aqueous solution is a commonly used disinfectant, which can be used for skin disinfection, medical device disinfection, etc. It can also be used as a solvent to dissolve drug ingredients, which helps the preparation and stability of drugs. It can also be used as a pharmaceutical intermediate to participate in the synthesis of certain drugs.
- Chemical raw materials: 2-Propanol can produce acetone through catalytic dehydrogenation or oxidation reaction; it can synthesize isopropyl ether with concentrated sulfuric acid; it can react with various acids to generate corresponding esters, which are commonly used in fragrance, coating, ink and other industries.
- Organic solvent: IPA can dissolve a variety of resins and pigments, so that coatings and inks have good fluidity and coating properties, and dry quickly. It is widely used in automotive paint, furniture paint, printing ink, etc. As a solvent, it can adjust the viscosity and drying speed of adhesives, improve the adhesion of adhesives to different materials, and is often used in the production of all-purpose adhesives, hot melt adhesives, etc. It is also an important solvent for cleaning semiconductors and electronic components. It can effectively remove oil, impurities and photoresist, etc. It is non-corrosive to electronic components and evaporates quickly, ensuring that the components dry quickly after cleaning.
- Other aspects: In cosmetics, IPA is used as a solvent and astringent to help dissolve ingredients such as spices and preservatives, and can also make the skin feel cool; IPA can be used as a food flavor and processing aid, and is used in extraction, separation and purification processes during food processing; it can be used as a fuel additive to increase the octane number of the fuel, improve combustion performance, and reduce exhaust emissions.
Exposure to high concentrations of IPA vapor can cause headaches, drowsiness, and eye, nose, and throat irritation. Workers should take protective measures and the workplace should be well ventilated. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Avoid direct sunlight. Keep the container sealed. Store separately from oxidants.
