Isopropyl Alcohol 70% USP Grade

Product Overview

Isopropyl Alcohol 70% USP Grade is a high-purity, clear, colorless liquid widely utilized as a solvent and critical cleaning agent in industrial and analytical environments. Also known as Isopropanol, IPA, or 2-Propanol, this formulation meets the rigorous standards of the United States Pharmacopeia (USP), ensuring low aldehyde content, minimal heavy metals, and consistent specific gravity. It is an essential chemical for manufacturing facilities requiring precise solvent properties for extraction, surface preparation, and equipment maintenance.

The 70% concentration offers an optimal balance of solvency and evaporation rate, making it miscible in water and most organic solvents. This versatility supports standardized workflows in chemical processing, laboratory research, and industrial degreasing. Alliance Chemical ensures that every lot adheres to strict quality controls, providing the reliability required for sensitive analytical chemistry methods (such as HPLC) and large-scale production processes.

Safety Precautions

Isopropyl Alcohol 70% is a flammable liquid and vapor. Keep away from heat, sparks, open flames, and hot surfaces. Store in a cool, well-ventilated place in tightly closed containers, preferably grounded to prevent static discharge during transfer. Use only non-sparking tools.

Personnel should wear appropriate Personal Protective Equipment (PPE), including chemical-resistant gloves and safety goggles, to prevent skin and eye contact. Use in a well-ventilated area to avoid inhalation of vapors. In case of spill, absorb with inert material and dispose of in accordance with local regulations. Refer to the Safety Data Sheet (SDS) for comprehensive handling instructions.
