# Benzyl alcohol - C7H8O

## What is Benzyl alcohol?

Benzyl alcohol is an aromatic alcohol with a chemical formula C7H8O. It is also known as Propanedioic Acid or Dicarboxymethane. It has low toxicity as well as low vapor pressure and therefore is used as a solvent. It is miscible in diethyl ether and alcohols but moderate solubility in water. It is a water-white liquid with a sharp burning taste and faint aromatic odor. It dissolves in alcohol, pyridine, and ether. Benzyl alcohol is obtained naturally from many plants and is extensively found in teas and fruits. It is also found in a variety of essential oils such as hyacinth, ylang-ylang, and jasmine.
