Isopropyl Alcohol 99.9% ACS Reagent Grade

Product Overview

Isopropyl Alcohol 99.9% ACS Reagent Grade (also known as Isopropanol, IPA, or 2-Propanol) is a high-purity solvent designed for critical applications in analytical laboratories and industrial manufacturing. With an assay of 99.9%, this clear, colorless liquid meets or exceeds the strict specifications established by the American Chemical Society (ACS). It features exceptionally low water content (typically <0.05%) and minimal non-volatile residue, making it the standard choice for sensitive processes where impurities could compromise results.

This reagent-grade solvent is essential for professionals in chromatography, spectroscopy, and electronics manufacturing. Unlike technical grades, ACS Reagent Grade IPA guarantees low limits on aldehydes, acidity, and trace metals. It allows for precise baseline stability in HPLC and GC workflows and ensures residue-free results when used for precision cleaning of optics and electronic components. Alliance Chemical supplies this material in a range of pack sizes, from 1-quart laboratory bottles to 330-gallon bulk totes, ensuring scalability for both research and full-scale production.

• Laboratory Analysis: Serves as a reliable solvent for sample preparation and extraction in wet chemistry.
• Surface Preparation: Utilized for critical surface preparation prior to coating or bonding in manufacturing.
• Chemical Synthesis: Acts as a reaction solvent and intermediate in the production of various industrial chemicals.

Safety Precautions

Isopropyl Alcohol is highly flammable and must be handled with care. Store in a cool, dry, well-ventilated area designated for flammables, away from heat, sparks, and open flames. Keep containers tightly closed when not in use to prevent evaporation and moisture absorption. Use appropriate Personal Protective Equipment (PPE), including splash-proof chemical goggles and solvent-resistant gloves (such as nitrile).

Ensure adequate ventilation or use exhaust hoods to maintain vapor concentrations below exposure limits. In the event of a spill, eliminate all ignition sources and contain with non-combustible absorbents. Follow all local, state, and federal regulations regarding hazardous waste disposal. Refer to the Safety Data Sheet (SDS) for detailed emergency response and transport information (UN 1219).
