Octylamine

CAS: 111-86-4

Overview

Octylamine (CAS 111-86-4 ) is a primary aliphatic amine used across specialty chemical manufacturing as a building block, curing agent, and pH modifier. It appears in supplier catalogs and formulation databases under the name 1-aminooctane.

Buyers in certain sectors use this as a distinct search term for procurement. In polymer and resin manufacturing, it functions as a curing agent and cross-linker for epoxy systems, influencing cure rate and final film properties.

This chemical is essential for coatings and adhesives. Personal care formulators incorporate it as an intermediate in the synthesis of conditioning agents, emulsifiers, and surfactant derivatives used in hair and skin products.

Flavor and fragrance chemists use it as a synthetic intermediate to produce nitrogen-containing aroma compounds. This is particularly useful in applications requiring fatty, amine-derived character for specific scent profiles.

It also serves as a pH-adjusting agent in specialty formulations where a long-chain amine is preferred over shorter-chain alternatives. This preference is often due to compatibility or volatility reasons in complex mixtures.

The product is supplied as a clear to pale yellow liquid in drum and IBC quantities suited to industrial procurement volumes. Technical grade is the standard commercial offering for most industrial applications.

High-purity grades are available for flavor, fragrance, and specialty chemical synthesis applications. Buyers should confirm purity specification and amine content with the supplier when sourcing for sensitive formulation use.
