Product Overview

Petroleum Ether 40-60°C AR (CAS No. 8032-32-4) is an analytical-reagent low-boiling petroleum hydrocarbon fraction defined by a 40-60°C distillation range. Because it is a mixture rather than a single compound, analytical suitability depends on controlled fraction composition, low non-volatile residue and reagent cleanliness rather than a fixed molecular identity.

The AR grade is intended for analytical extraction, sample cleanup, gravimetric work-up and conventional laboratory methods requiring a clean volatile non-polar solvent. It is suitable for partition and recovery studies that require the specified boiling point range.

Typical Applications

• Analytical solvent extraction
• Sample cleanup of non-polar components
• Gravimetric extraction procedures
• Recovery and partition studies
• Preparation of hydrophobic analytical solutions
• Residue-related analytical work
• Conventional laboratory quality-control extraction

Common Synonyms

• Petroleum ether
• Petroleum benzine
• Ligroin
• Benzine
• Light petroleum

Storage Conditions

Store tightly closed and protect from evaporation and analytical contamination. Prevent cross-contamination with other boiling-range fractions or non-volatile solvents that could affect analytical residue.
