Cyclohexylamine (CAS 108-91-8) is a high-purity organic compound widely used as a versatile chemical intermediate and functional additive in multiple industrial sectors. Also known as cyclohexanamine or aminocyclohexane, this clear to slightly yellowish liquid with a characteristic amine odor serves as a key building block for advanced chemical synthesis.

Product Overview

Chemical Name: Cyclohexylamine

CAS Number: 108-91-8

Molecular Formula: C₆H₁₃N

Appearance: Colorless to pale yellow clear liquid

Solubility: Miscible with water and most common organic solvents (alcohols, ethers, ketones)

Cyclohexylamine is a strong base aliphatic amine, valued for its reactivity and ability to form derivatives that deliver performance benefits in end-use applications.

Key Applications

Cyclohexylamine functions as an essential intermediate and additive across several high-demand industries:

  • Corrosion Inhibition — Acts as an effective volatile corrosion inhibitor in boiler water treatment, steam systems, and closed-loop cooling circuits, forming protective films on metal surfaces to prevent rust and extend equipment life.
  • Rubber & Polymer Industry — Serves as a critical precursor for vulcanization accelerators (such as CBS – N-cyclohexyl-2-benzothiazolesulfenamide), improving rubber processing, elasticity, durability, and curing efficiency in tires, belts, hoses, and industrial rubber goods.
  • Chemical Synthesis — Used in the production of pharmaceuticals intermediates, agrochemicals (pesticides and insecticides), dyestuffs, emulsifiers, plasticizers, and synthetic sweeteners.
  • Water Treatment — Employed in industrial water systems as a neutralizing amine, pH regulator, and oxygen scavenger component to control corrosion and maintain system integrity.
  • Other Uses — Found in dry-cleaning soaps, antistatic agents, latex coagulants, and various specialty chemical formulations.

Its multi-functional nature makes cyclohexylamine a preferred choice for manufacturers seeking reliable, high-performance raw materials.

Technical Advantages

  • Excellent solubility and compatibility with aqueous and organic systems
  • Strong basicity for effective neutralization and film-forming properties
  • High reactivity enabling efficient synthesis of downstream derivatives
  • Proven performance in demanding industrial environments

Safety & Handling Information

Cyclohexylamine is classified as a flammable liquid and corrosive substance. It causes severe skin burns and eye damage, and is harmful if swallowed, inhaled, or absorbed through skin. Handle with appropriate PPE (chemical-resistant gloves, goggles, protective clothing, and respiratory protection in poorly ventilated areas). Store in tightly closed containers in a cool, well-ventilated location away from strong oxidizers, acids, and ignition sources. Refer to the latest Safety Data Sheet (SDS) for complete hazard, first-aid, and disposal guidelines.
