Product Description | Isopropyl Alcohol CAS 67-63-0
Basic Introduction
Isopropyl Alcohol (IPA) belongs to secondary alcohol, being an isomer of n-propanol. It appears as a clear, colorless and highly flammable liquid with a distinctive smell resembling a blend of ethanol and acetone.
Excellent Solubility Performance
It boasts outstanding miscibility: fully mixes with water, ethanol, ether, benzene, chloroform and most common organic solvents, and is able to form azeotropic mixture with water, making it a powerful universal solvent for industrial cleaning and formulation.
Key Safety & Hazard Reminders
Flammability Risk: Its volatile vapor is prone to forming explosive blends with air, with the volume explosion range between 2.0% and 12%, classified as a medium-risk flammable hazardous chemical.
Irritation & Toxicity: Inhalation of vapors will mildly irritate eyes, nasal cavity and throat; the product can penetrate and be absorbed by human skin.
Toxicity Feature: Vapor toxicity is double that of ethyl alcohol, while oral ingestion brings lower toxicity compared to ethanol.
Core Product Highlights
Strong dissolving power, quick volatilization without stubborn residues, widely applicable in surface cleaning, disinfection, chemical synthesis and electronic component wiping scenarios.
