Are there different grades of isopropyl alcohol?
Yes, CAS 67-63-0 isopropyl alcohol is produced in several distinct grades based on purity, impurity limits, and intended applications:
Industrial grade (≥99%): The most common grade, with moderate impurity limits. Used for coatings, inks, metal degreasing, and fuel additives.
Pharmaceutical grade (≥99.5%): Meets strict regulatory standards (e.g., FDA, EP) with ultra-low levels of metal ions (<0.1 ppm) and organic impurities. Used in drug synthesis, medical device disinfection, and personal care products.
Electronic grade (≥99.9% / ≥99.99%): The highest purity grade, with metal ion content ≤1 ppb (for 99.99% grade). Used in semiconductor manufacturing, LCD panel cleaning, and photovoltaic cell production.
Disinfectant grade (60–70%): Pre-diluted with water for optimal disinfection efficacy. Used in healthcare, laboratories, and household cleaning.
