Petroleum Ether ACS Reagent Grade

Product Overview

Petroleum Ether ACS Reagent Grade, also referred to as Petroleum Spirit or Ligroin, is a highly refined mixture of aliphatic hydrocarbons (C5-C6). This ACS-grade solvent is engineered for applications requiring high volatility and minimal residue. With a typical assay of 99.8% and strict limits on impurities, it ensures lot-to-lot consistency essential for sensitive analytical workflows, including Gas Chromatography (GC) and High-Performance Liquid Chromatography (HPLC).

The solvent features an exceptionally low residue on ignition (typically 0.0005%), preventing contamination in gravimetric analysis and spectroscopic measurements. Its low boiling point facilitates rapid evaporation, making it an efficient choice for solvent exchange and sample concentration. Alliance Chemical provides this material in packaging ranging from 1 Liter lab quantities to 55 Gallon drums for industrial scale-up, all verified via GC-FID and ICP-MS analysis.

Common Applications

• HPLC Mobile Phase: Utilized as a non-polar volatile component for the separation of organic compounds in chromatography.
• Extraction Solvent: High volatility and low polarity make it ideal for isolating active ingredients and essential oils.
• Organic Synthesis: Acts as an inert reaction medium for hydrocarbon-soluble substrates.
• Equipment Cleaning: Effective degreaser for precision laboratory glassware and industrial equipment due to rapid drying times.
• Sample Preparation: Used in GC sample cleanup and solvent exchange protocols.

Safety and Handling

Petroleum Ether is a flammable liquid (Category 2) and must be handled with care. Store in a cool, well-ventilated area away from ignition sources, heat, and direct sunlight. Keep containers tightly closed when not in use. This product is classified as UN 3295, Petroleum Distillates, N.O.S., Class 3, PG II for transport.

Operators should wear appropriate Personal Protective Equipment (PPE), including chemical-resistant gloves and safety goggles. Use in a fume hood or well-ventilated space to avoid inhalation of vapors, which may cause drowsiness or dizziness. Refer to the Safety Data Sheet (SDS) for comprehensive handling instructions and emergency response procedures.
