Dicyclohexylamine

Dicyclohexylamine (CAS 101-83-7), commonly abbreviated as DCHA, is a secondary aliphatic amine used as a chemical intermediate, catalyst, and neutralizing agent across pharmaceutical, polymer, and specialty chemical manufacturing.

Its basicity and reactivity make it a building block for a range of downstream synthesis processes. In pharmaceutical manufacturing, DCHA forms stable salt complexes with acidic active ingredients, improving crystallization and purification.

This material assists in the handling of intermediates during synthesis. Rubber and polymer producers use it as a vulcanization accelerator precursor and corrosion inhibitor component in metalworking and vapor-phase protection formulations.

In organic synthesis and catalysis, DCHA acts as a base catalyst for condensation and esterification reactions. This is particularly useful where a hindered, non-nucleophilic amine is required for specific chemical transformations.

It also appears in flavor chemistry applications under FEMA-regulated use, where it contributes to specific fragrance and flavor profiles in approved formulations. The compound is supplied as a colorless to pale yellow liquid.

Standard packaging includes drum and IBC options for industrial scale. Technical grade is the most common commercial form, with pharmaceutical-grade material available to meet purity requirements for API intermediate applications.

Buyers should confirm specification sheets against their synthesis or regulatory requirements, as purity thresholds vary by application. Adherence to USP or EP standards may be necessary depending on the final use case.
