n-Hexylamine · 1-Aminohexane · hexan-1-amine · ≥99% commercial, LR and AR grades
Hexylamine is a straight-chain C6 primary amine: small enough to stay a mobile liquid, long enough to carry a real hydrophobic tail. It is used to build corrosion inhibitors, surfactants and emulsifiers, and as an intermediate in pharmaceutical, agrochemical, rubber and dye synthesis. Chelora Amines supplies it worldwide and across India, in UN-specification packaging with a batch-wise COA and SDS.
72.06 + 13.10 + 14.01 + 2.02 = 101.19 g/mol
Hexylamine, also called n-hexylamine, 1-aminohexane or hexan-1-amine, is a clear, colourless to pale yellow, flammable liquid with a fishy, ammoniacal odour. It boils at about 131 °C and dissolves only partly in water — around 12 g per litre at 20 °C — but mixes freely with alcohols, ethers and hydrocarbons.
It sits in the middle of the primary alkylamine series. Shorter amines such as n-Butylamine are water-miscible and volatile; longer ones such as Octylamine are oily and barely water-soluble. Hexylamine strikes a useful balance: an unhindered, strongly basic nitrogen with a C6 tail that makes its salts and amides surface-active and film-forming.
It is manufactured by catalytic amination of 1-hexanol with ammonia and hydrogen, or by hydrogenation of hexanenitrile. Di-n-hexylamine, residual hexanol and water are the impurities that matter, and all three are controlled in the specification.

Hexylamine is an unhindered, strongly basic primary amine. It reacts quickly with electrophiles, and its C6 chain carries through into products that need oil solubility or surface activity.
Reacts with acid chlorides, anhydrides and esters to give N-hexyl amides used as intermediates and dispersing agents.
RCOCl + C₆H₁₃NH₂ → amideAdds to carbon disulfide to give hexyldithiocarbamates for rubber and fungicide chemistry.
CS₂ + C₆H₁₃NH₂ → dithiocarbamateCondenses with aldehydes and ketones to Schiff bases, which reduce to secondary amines.
RCHO + C₆H₁₃NH₂ → imineNeutralises fatty, phosphoric and carboxylic acids to hexylammonium salts that film metal surfaces.
acid + C₆H₁₃NH₂ → saltAdds across isocyanates to give N-hexyl ureas for agro and pharma intermediates.
RNCO + C₆H₁₃NH₂ → ureaOpens epoxides to amino alcohols and acts as a monofunctional modifier for epoxy resins.
epoxide + C₆H₁₃NH₂ → amino alcoholTakes up ethylene oxide to give ethoxylated hexylamines, non-ionic to cationic surfactants.
C₆H₁₃NH₂ + n EO → ethoxylateWith a conjugate-acid pKa near 10.6 it neutralises HCl released in acylation and sulfonylation steps.
pKa ≈ 10.6 at 25 °CProcess notes. Hexylamine has a flash point near 28 °C, so it is flammable at warm ambient temperature. Additions to acid chlorides and isocyanates are strongly exothermic — dose with cooling, keep transfers earthed and blanket vessels with nitrogen.
Discuss your processHexylamine is made by catalytic amination, and the route sets the impurity profile: higher amines from over-reaction, and residual alcohol or nitrile from incomplete conversion.
1-Hexanol, or hexanenitrile, is fed with ammonia and hydrogen to a fixed-bed reactor.
Over a nickel or cobalt catalyst at elevated temperature and pressure, the alcohol is converted to the primary amine; excess ammonia holds down secondary amine.
The reactor delivers hexylamine with ammonia, water, unreacted hexanol and some di- and tri-n-hexylamine.
Ammonia is recovered and recycled; water is split off and fractional distillation separates mono-, di- and tri-hexylamine.
Product is tested for assay, di-hexylamine, hexanol, water and colour, then filled under nitrogen into carboys, drums, totes or bulk containers.
Di-n-hexylamine is the main by-product. At high levels it upsets the stoichiometry of an acylation and leaves a secondary-amide impurity. Residual 1-hexanol comes from incomplete conversion; it is inert in most salt-forming work but competes in reactions with acid chlorides and isocyanates.
Water matters wherever the next step is moisture sensitive, and colour matters in surfactant and emulsifier formulations. Where a registration dossier or a validated process names limits, send them with the enquiry and we will match the batch rather than send the standard cut.
Twelve months in sealed original packing, kept cool and out of sunlight, is the normal working figure. Hexylamine picks up carbon dioxide from air and forms a carbamate that shows as haze or a white crust at the drum mouth.
Keep drums closed between draws, blanket tanks with nitrogen where you can, and re-check assay, water and colour before a critical batch from older stock. A retained sample of every batch is held here.
Tell us the reaction and the limits that matter and we will confirm the grade. Commercial grade covers most production use; LR and AR grades are available for laboratory, method development and analytical work.

Chain length and ring structure change boiling point, water solubility and flash point far more than they change basicity. These four are often considered for the same job and are not interchangeable in a validated process.

Hexylamine is checked before dispatch and each consignment leaves with the paperwork your QC, stores and accounts teams need on day one.
The numbers on a Certificate of Analysis are only useful if you know how they were produced. These are the methods behind the figures on ours, and the checks worth repeating at your own goods-inward.
Separates the amine from related amines and residual solvents in one run, and gives both the assay and the impurity profile that matter to your reaction.
An independent check on total amine content, useful as a quick goods-inward confirmation before a drum is released to production.
Water determination, which matters wherever the next step is moisture sensitive or the amine feeds an anhydrous reaction.
A visual platinum–cobalt comparison. A rising colour value is the earliest sign that a pack has been exposed to air or held too long.
Fast confirmation of identity and strength, and a simple way to spot a wrong pack or a contaminated drum.
Gravimetric residue and trace metal checks, which matter for catalytic steps and regulated formulations.
A sample from every dispatched batch is held here, so a query months later can be settled against the original material.
The batch number on the label ties back to the COA, the test record and the supply lot, which is what your auditor will ask to see.
Where your customer or regulator needs an independent result, we can arrange analysis at a NABL-accredited laboratory before dispatch.
