Cyclohexylamine
A cycloaliphatic primary amine: cyclohexylamine's saturated six-membered ring gives it a distinct reactivity and steric profile from straight-chain amines, built on across sweetener, rubber, corrosion-inhibitor and pharmaceutical chemistry.
Chelora Chemicals supplies cyclohexylamine to specialty chemical, rubber and pharmaceutical-intermediate manufacturers worldwide, with full GHS documentation on every consignment.

What Cyclohexylamine is used for
Cyclohexylamine is a colourless to pale yellow liquid with a strong fishy, amine-like odour, carrying a primary amine group on a saturated six-membered carbon ring rather than a straight chain. That ring structure gives it a distinct reactivity and steric profile compared with chain amines of similar carbon count.
Cyclohexylamine is best known as the intermediate behind the cyclamate artificial sweetener, and as the precursor for sulfenamide rubber-vulcanization accelerators. It also serves as a corrosion inhibitor, a printing-ink flushing aid, and a building block for sulfonamide hypoglycemic pharmaceuticals such as glibenclamide, glipizide and cilostazol.
Ring versus chain amine chemistry
- Hexylamine straight six-carbon chain amine — flexible, more volatile. See that page.
- Cyclohexylamine (this product) cyclic six-carbon ring amine — rigid, distinct steric profile.
- Isophorone diamine substituted cyclohexane diamine — epoxy and polymer chemistry. See that page.
Appearance and handling character
Cyclohexylamine is flammable and corrosive — harmful if swallowed or in contact with skin, causes severe skin burns and eye damage, and is suspected of damaging fertility — a hazard profile that calls for careful PPE and exposure control throughout handling.

How we supply Cyclohexylamine
Chelora Chemicals is a supplier and sourcing partner, not a manufacturer. Cyclohexylamine's use in pharmaceutical synthesis means assay and impurity-profile documentation matter as much as price — that shapes how we manage this line.
We place your order with whichever qualified producer best matches your required grade, your price point and your delivery window.
We keep a second qualified source on this line, so a single-plant disruption never becomes your production problem.
- Assay confirmed before we quote. Purity matters to downstream pharmaceutical and sweetener synthesis.
- Flammable-liquid logistics managed end to end. Classification, labelling and carrier compliance confirmed before booking.
- Reproductive-hazard documentation filed correctly. Every shipment carries the correct hazard declarations.
- Scheduled call-off scheduling. We hold contracted tonnage and release it against your consumption calendar.
- Batch traceability to the producing plant. Full chain of custody documentation on request.
- Export machinery handled in-house. Classification, approved packing, labelling, freight booking and customs paperwork are ours to manage.

Flammable, corrosive, and a reproductive-hazard caution
Cyclohexylamine's combination of flammability, corrosivity and suspected reproductive toxicity makes PPE and exposure control the central handling concerns. The summary below is orientation only — the safety data sheet supplied with your specific batch is the authoritative document.
Classified hazards
H226Flammable liquid and vapour.H302Harmful if swallowed.H312Harmful in contact with skin.H314Causes severe skin burns and eye damage.H361Suspected of damaging fertility or the unborn child.
Always read the SDS issued with your specific batch. Eliminate ignition sources; handle with chemical-resistant gloves, splash goggles and adequate ventilation; avoid unnecessary exposure.
Storage
Store in tightly closed containers away from heat, sparks and open flame, in a well-ventilated area rated for flammable liquids.
Handling
Use with local exhaust ventilation and bond/ground equipment during transfer to control static discharge. Minimise skin and eye contact with appropriate PPE.
Transport
Shipped in accordance with its flammable/corrosive classification. We confirm and document packing group and exact classification for your specific shipment and destination.
Every batch, documented
We verify documentation before dispatch so there are no surprises at your incoming-goods bench.
Specification agreed
Assay confirmed against your process requirement before order placement.
Producer batch testing
The producing plant tests each batch against the agreed specification before release.
Documentation review
COA, SDS and transport paperwork checked by our desk before the shipment is booked.
Traceable dispatch
Each shipment is traceable to its producing batch, with full chain-of-custody records on request.
How cyclohexylamine is made
Cyclohexylamine is produced industrially by the catalytic hydrogenation of aniline, or by hydrogenation of cyclohexanone oxime/nitrocyclohexane routes, giving the saturated cyclic amine after purification and fractional distillation.
We do not publish operating process parameters here; this is background only. Full technical and safety documentation accompanies every shipment, and any process-specific detail you need is best confirmed directly with our technical desk.
