Isopropyl Alcohol 70% USP Grade

Product Overview

Isopropyl Alcohol 70% USP Grade is a clear, colorless liquid that serves as a versatile solvent and cleaning agent across analytical and industrial environments. This USP-NF compliant composition combines isopropanol with water to deliver consistent performance in extraction, tissue cleaning, and sample preparation. The product adheres to stringent quality controls, including residual solvent limits and low impurity levels, to support applications requiring high purity and reliable lot-to-lot consistency.

With broad miscibility in water and many organic solvents, the formulation supports standardized workflows in laboratories, pharmaceutical manufacturing, and industrial cleaning processes. The documented specifications—such as assay range, color, specific gravity, and low aldehydes—are designed to meet industry expectations for quality, equipment compatibility, and regulatory compliance while maintaining convenient handling and storage characteristics. This product is ideal for analytical chemistry methods, including use as a mobile phase component in reversed-phase HPLC, as well as a solvent for extraction and surface degreasing in manufacturing settings.

Safety Precautions

Handle in a well-ventilated area with appropriate PPE, including chemical-resistant gloves and splash goggles. Store in a cool, ventilated space away from heat, open flames, and incompatible materials (strong oxidizers and acids). Use containers made of HDPE or glass to minimize container reactions and ensure secondary containment for spill control.

In case of exposure, follow standard emergency procedures: use eye wash stations for splashes, remove contaminated clothing, and seek medical attention for signs of irritation or dizziness. This product is flammable; keep away from ignition sources and ensure proper grounding and bonding during transfer to prevent static discharge. Refer to the SDS for detailed handling, transport, and first-aid measures.
