What is Benzyl Alcohol CAS 100-51-6?

Benzyl Alcohol CAS 100-51-6 is a clear, colorless aromatic primary alcohol with the formula C7H8O. It is also called phenylmethanol or benzenemethanol and is used as a solvent, epoxy-curing additive, pharmaceutical preservative and fragrance ingredient.

Why is Benzyl Alcohol used in epoxy resin and coating systems?

It lowers viscosity and improves compatibility between epoxy resin and amine or polyamide hardeners. In flooring and adhesive formulations it can also help accelerate cure, improve leveling and produce a more workable coating system.

How is Benzyl Alcohol used as a pharmaceutical preservative?

In multi-dose injectable and other pharmaceutical products, benzyl alcohol is used at controlled preservative concentrations for its bacteriostatic activity. Pharm or BP/USP grade should be selected for drug-related applications, with the exact concentration and route of use confirmed by the formulator.

What solvent and purity properties should be checked for this product?

The listing specifies GC purity of at least 99.90%, APHA color of 10 or less, water content of 0.1% or less, and benzaldehyde below 300 ppm. It has a boiling point near 205.3 C, density of about 1.043-1.048 g/mL and limited water solubility of about 4 g/100 mL, while it is miscible with ethanol and ether.

How should Benzyl Alcohol be stored to prevent oxidation?

It slowly oxidizes in air to benzaldehyde and benzoic acid, so it should be kept in tightly sealed drums or IBC tanks under a nitrogen blanket when possible. Store in a cool, well-ventilated area away from heat, ignition sources and direct sunlight.

Product Description

Benzyl Alcohol, CAS 100-51-6, is a clear, colorless aromatic primary alcohol.

Synonyms: Phenylmethanol; Benzenemethanol; Alpha-hydroxytoluene; Phenylcarbinol; Benzylic alcohol.

CAS: 100-51-6.

It has a mild aromatic characteristic odor and a boiling point of about 205.3 °C.

It has a GC purity of not less than 99.90% and an APHA color of not more than 10.

It has a specific gravity of about 1.043–1.048 and a refractive index of about 1.538–1.541 at 20 °C.

It is miscible with ethanol and ether and has limited water solubility of about 4 g/100 mL.

It is an excellent solvent for waxes, resins, shellac and epoxy hardeners, and lowers viscosity in epoxy systems.

It is used as a fixative in perfumes and soap essences to slow the evaporation of volatile scent components.

It is used as a preservative in lotions, shampoos and creams, and as a solvent for fragrances.

It is used as a bacteriostatic agent and local anesthetic in pharmaceutical injectable formulations.

It is used as a solvent and viscosity reducer in paint strippers, inks and photographic developing solutions.

It is also used as a solvent and viscosity reducer for epoxy resin curing agents in floor coatings.

Confirm appearance, odor, GC purity, APHA color, specific gravity, refractive index, acidity, water content, benzaldehyde content, boiling point, flash point and solubility.

Store in a cool, dry, well-ventilated area in tightly sealed, light-resistant containers under nitrogen blanket where possible.

Benzyl Alcohol slowly oxidizes in air to benzaldehyde and benzoic acid, so keep containers tightly closed and away from heat and ignition sources.

Confirm packaging with the requested quantity and destination requirements.
