Product Overview

Benzyl Alcohol 99.5% GC (CAS No. 100-51-6) is a primary aromatic alcohol containing a hydroxymethyl group directly attached to a phenyl ring. Its molecular structure combines the hydrogen-bonding character of an alcohol with the solvating behaviour of an aromatic system, enabling interaction with a broad range of compatible organic compounds. Under appropriately selected chromatographic conditions, benzyl alcohol can be introduced and resolved directly by gas chromatography.

The GC grade is intended for gas-chromatographic sample preparation, method development, solvent-blank evaluation, and quality-control procedures requiring benzyl alcohol with controlled chromatographic purity. Its comparatively low volatility makes it useful as a high-boiling sample-preparation medium in selected capillary GC procedures, including validated residual-solvent methods, while its defined assay supports comparative, recovery, and impurity-separation studies involving benzyl alcohol.

Typical Applications

• High-boiling sample-preparation solvent in validated gas-chromatographic procedures.
• Diluent or dissolution medium for compatible samples undergoing capillary GC analysis.
• Preparation of solvent blanks for evaluating chromatographic background and system cleanliness.
• Preparation of comparative, spiked, and recovery-test solutions where GC-grade benzyl alcohol is method-appropriate.
• GC determination of benzyl alcohol in suitably prepared samples and formulations.
• Investigation of benzaldehyde and other chromatographically detectable impurities associated with benzyl alcohol.
• Method-development studies involving the retention and separation of benzyl alcohol from related aromatic alcohols, aldehydes, and volatile organic compounds.

Common Synonyms

Storage Conditions

Store in a tightly closed container in a cool, dry, and well-ventilated area. Protect from direct light, excessive heat, prolonged exposure to air, evaporation, and contamination by other volatile organic compounds. Minimise unnecessary container opening and use clean, solvent-compatible dispensing equipment to preserve chromatographic cleanliness and limit oxidation-related impurity formation.
