Description

Petroleum Ether CAS NO 64742-89-8 is a highly volatile, low-boiling hydrocarbon fraction derived from petroleum refining, primarily consisting of pentanes and hexanes. This solvent is valued for its excellent solvency power, rapid evaporation rate, and relatively low toxicity, making it a critical processing aid in numerous industrial applications. It is an essential material for laboratories, pharmaceutical manufacturers, and chemical processors requiring a reliable, non-polar extraction and cleaning medium.

Application

• Extraction Solvent: Widely used for the extraction of oils, fats, waxes, and natural products from plant and animal matter.
• Laboratory Reagent: Serves as a common solvent for chromatography, recrystallization, and as a reaction medium in organic synthesis.
• Cleaning & Degreasing Agent: Effective for precision cleaning and degreasing of metal parts, optical components, and electronic assemblies.
• Pharmaceutical Processing: Utilized in the purification and processing of active pharmaceutical ingredients (APIs) and intermediates.
• Adhesive & Polymer Industry: Acts as a solvent in the formulation of adhesives, rubber cements, and for the dissolution of certain polymers.
• Fuel & Starting Fluid: Used as a component in some specialty fuels and as a starting fluid for engines.

Quality Control

Our Petroleum Ether is produced under stringent quality management systems. Each batch is tested to ensure consistent composition, purity, and performance characteristics such as boiling range, evaporation residue, and water content. Certificates of Analysis (COA) documenting these parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its highly volatile nature, keep containers tightly sealed when not in use to prevent evaporation and maintain purity. Observe all local regulations for the storage of flammable liquids.
