What is the purity of isopropyl alcohol IPA CAS 67-63-0?

Common Purity & Uses

70% IPA (30% water): Optimized for germ killing-water enhances penetration of microbial cell walls and protein coagulation, boosting disinfection efficacy. Aligns with CDC's recommended 60-90% range for healthcare disinfection.

91% IPA: Balances performance for electronics cleaning (circuit boards, general surfaces) and household tasks. Delivers stronger cleaning power than 70% IPA with faster evaporation.

99% (99.9%) IPA (Technical/Lab Grade): High-purity formula ideal for degreasing, adhesive removal, glassware cleaning, and applications requiring rapid drying or minimal moisture.

Ultra-Pure IPA (99.99%–99.999%): Critical for advanced electronics manufacturing (e.g., semiconductors), where minute impurities could damage sensitive microchips.
