What is 1-Octanol CAS 111-87-5?

1-Octanol, also called n-octanol, capryl alcohol, or octyl alcohol, is a straight-chain C8 primary fatty alcohol with the molecular formula C8H18O and molecular weight about 130.23 g/mol. It is a colorless, oily liquid with a mild fatty-citrus or rose-like odor and is widely used as a chemical intermediate.

How does 1-Octanol differ from 2-ethylhexanol?

1-Octanol is the linear primary alcohol with the hydroxyl group at the end of an unbranched C8 chain. 2-Ethylhexanol is a branched C8 isomer commonly used for large-volume plasticizer production; the linear structure of 1-octanol gives different odor, solvent, esterification, and application properties.

What purity, appearance, and storage conditions are typical for 1-Octanol?

The material is normally supplied as a clear, colorless oily liquid with minimum purity around 99% for industrial and reagent grades. It should be stored in closed containers in a cool, ventilated area away from ignition sources and oxidizing agents because it is combustible and slightly soluble in water.

Product Description

1-Octanol CAS 111-87-5 is a straight-chain C8 primary fatty alcohol, also known as n-octanol, with the formula C₈H₁₈O and EINECS 203-917-6.

Synonyms: n-Octanol; Capryl alcohol; Octyl alcohol; Alcohol C8; n-Octyl alcohol.

CAS: 111-87-5.

Molecular formula: C₈H₁₈O.

It is a colorless, oily liquid with a mild fatty-citrus or rose-like odor.

1-Octanol is the linear primary alcohol with the hydroxyl group at the end of an unbranched C8 chain.

Its linear structure gives different odor, solvent, esterification and application properties compared with branched C8 isomers such as 2-ethylhexanol.

It is used to synthesize esters for plasticizers, fragrances and flavors.

It is also used as an extraction solvent, a defoamer in fermentation and aqueous industrial systems, and a surfactant or coating intermediate.

The typical purity (GC) is about 99.0% or higher, with a refractive index of about 1.428-1.430.

The boiling point is about 194-195 °C, and the flash point is about 81 °C.

The moisture content is typically not more than 0.1%, and the acid value not more than 0.1 mg KOH/g.

Store in closed containers in a cool, ventilated area away from ignition sources and oxidizing agents.

Protect from heat and ignition sources, and keep containers closed when not in use.

Confirm appearance, assay, refractive index, moisture, acid value and grade as required.

Use suitable eye and skin protection during handling, and wash skin contact with soap and water.

Confirm packaging with the requested quantity and destination requirements.
