Product Overview
Isopropyl Alcohol 91% USP Grade (Isopropanol, 2-Propanol) is a high-purity, colorless solvent formulated for demanding industrial, laboratory, and manufacturing environments. Containing approximately 91% alcohol and 9% water by volume, this concentration offers a slightly lower evaporation rate compared to anhydrous grades, allowing for longer surface contact time in cleaning and degreasing applications. As a USP-grade material, it meets strict purity monographs, ensuring low aldehyde content and minimal impurities.
This solvent is widely utilized as a polar solvent in botanical extraction, a processing aid in pharmaceutical manufacturing, and a critical cleaner for electronics and 3D printing post-processing. Its miscibility with water and most organic compounds makes it an essential component in coatings, inks, and chemical formulations. Isopropyl Alcohol 91% is supplied with full lot traceability to ensure consistent performance in regulated workflows.

Common Applications
- Botanical Extraction: Used as a primary solvent for extracting essential oils and organic compounds due to its high solvency power.
- Electronics Manufacturing: Effective for cleaning printed circuit boards (PCBs), removing flux residues, and cleaning fiber optics.
- 3D Printing: Standard solvent for washing and post-processing SLA/DLP resin prints to remove uncured resin.
- Industrial Cleaning: Removes oils, greases, gums, and inks from machinery and precision equipment without leaving conductive residues.
- Process Solvent: Acts as a carrier solvent in the formulation of lacquers, coatings, and adhesives.
Safety & Handling
Flammability Warning: Isopropyl Alcohol 91% is a Class 3 Flammable Liquid. Keep away from heat, sparks, open flames, and hot surfaces. Store in a cool, well-ventilated place approved for flammables. Ground/bond container and receiving equipment during transfer to prevent static discharge.
PPE Requirements: Wear protective gloves (butyl rubber or nitrile), chemical splash goggles, and flame-retardant clothing when handling. Ensure adequate ventilation to keep vapor concentrations below OSHA permissible exposure limits. Refer to the Safety Data Sheet (SDS) for comprehensive first aid and emergency procedures.
Benefits
- High Solvency: Dissolves a wide range of non-polar compounds, oils, and resins.
- Controlled Evaporation: The 91% concentration balances drying speed with surface contact time for effective cleaning.
- Low Residue: Evaporates cleanly, leaving minimal residue on treated surfaces.
- Bulk Availability: Scalable sizing from lab-grade quarts to production-ready totes.
