Benzyl Alcohol Extra Pure

Whatsapp Order

Benzyl Alcohol Extra Pure is a high-purity, clear, colorless liquid with a mild aromatic odor, widely used in laboratory chemistry for analytical, synthetic, and preparative applications. It functions as a versatile solvent for inks, resins, waxes, and dyes, and plays a key role in organic synthesis, particularly in esterification and benzylation reactions. Its moderate polarity and low volatility make it valuable in sample preparation, chromatography, and pharmaceutical research. The extra pure grade guarantees minimal levels of impurities, ensuring reliable performance in high-precision laboratory procedures. Benzyl alcohol should be handled with care and stored in a tightly sealed container in a cool, dry place, away from strong oxidizing agents.

Description

USES

Primary Uses

Solvent in Organic and Analytical Chemistry
- Serves as a polar solvent for inks, dyes, resins, cellulose esters, and oils in experimental setups.
- Used in extraction, recrystallization, and spectroscopy involving slightly polar compounds.
Reagent in Organic Synthesis
- Acts as a starting material or intermediate for synthesizing benzyl esters, benzyl ethers, and benzaldehyde in lab-scale reactions.
Demonstration of Alcohol Reactions
- Used to teach oxidation of alcohols, particularly oxidation to benzaldehyde or benzoic acid with appropriate oxidizing agents (e.g., KMnO₄, PCC).
Preparation of Benzyl Derivatives
- Involved in nucleophilic substitution reactions, esterification, and as a protecting group precursor in multistep syntheses.

Secondary Uses

Solvent for UV-Vis and IR Spectroscopy
- Useful for dissolving organic analytes in spectral studies, especially where water or more polar solvents are not compatible.
Model Compound in Physical Chemistry Labs
- Used in experiments involving boiling point elevation, freezing point depression, and Raoult’s law due to its manageable volatility.
Antibacterial Solvent in Biological Sample Prep
- Occasionally used to prepare biological slides or solutions in microbiology or molecular biology labs due to its mild antiseptic properties.
Intermediate in Drug/Formulation Research
- Investigated in lab-scale pharmaceutical formulation studies for its role in drug solubilization and topical delivery systems.
