1-Pentanol
1-Pentanol, also called n-pentanol or n-amyl alcohol, is the straight-chain form of amyl alcohol with five carbon atoms. It is supplied at 99.80% minimum amyl alcohol content with isoamyl alcohol at 0.10% maximum. It is used as a solvent, an organic synthesis raw material, a plasticizer raw material and a flavour and pharmaceutical intermediate.
What You Get With This Grade
- Amyl alcohol content 99.80% minimum, with the isomer and aldehyde impurities both specified
- n-Valeraldehyde held at 0.03% maximum, which matters when the alcohol is going into a flavour
- Acid as acetic acid 0.005% maximum and water 0.06% maximum
- HS code 2905199090 and UN number 1105 published for customs and transport planning
Technical features
- Straight-chain form of amyl alcohol, one of eight isomers with the formula C5H11OH
- Less dense than water, with vapours heavier than air
- Flash point 91 °F and boiling point 280 °F
- EC number 200-752-1, UN number 1105, HS code 2905199090
Where 1-Pentanol Is Used
Solvent use
Used as a solvent and to make other chemicals.
Organic synthesis and plasticizer feedstock
An organic synthesis raw material and a plasticizer raw material.
Food flavours and pharmaceuticals
Used in the production of food flavours, flavours and pharmaceutical raw materials.
Mineral flotation and boiler water
Used as a flotation agent for non-ferrous metals and an antifoaming agent for boiler water.
Downstream chemicals
The main industrial raw material for producing pentene, amylamine and bromopentane.
How 1-Pentanol Looks and Ships
Buyers This Grade Is Built For
- Flavour houses needing the straight-chain isomer rather than the mixture
- Mineral processing operations using it as a flotation agent
- Boiler water treatment formulators needing an antifoam
- Synthesis plants making pentene, amylamine or bromopentane
What It Stops Going Wrong
- Buying a pentanol mixture when the route needs the straight-chain isomer changes the product
- Residual valeraldehyde in the alcohol carries an odour into a flavour application
- Water and acid drift in an alcohol destabilise downstream esterification
- UN number and HS code missing from the offer slows customs clearance

How It Ships and How to Store It
Packing
- Galvanised iron drum, 165 kg net per drum
- ISO tank for bulk
- Can be packaged according to user requirements
Storage and transport
- Store as a flammable liquid away from ignition sources
- Vapours are heavier than air, so keep low-level ventilation in the store
How the Lot Is Released
Amyl alcohol content, isoamyl alcohol, n-valeraldehyde, water, acid and colour are checked against the quality index before release.
What We Can Change
165 kg drum or ISO tank, packed according to user requirements.
Against the Alternatives
1-Pentanol is the single straight-chain isomer at 99.80% minimum. The pentanol mixture is a blend of 62-68% n-amyl alcohol and 32-38% 2-methylbutanol at 99.0% minimum total content, and is the cheaper solvent choice. Isoamyl alcohol is the branched 3-methyl-1-butanol isomer used in flavour and fragrance work. Choose by whether the isomer identity matters downstream.
Handling 1-Pentanol on Your Site
Written for the person who receives the drum, not for a brochure.
- Check the n-valeraldehyde figure of 0.03% maximum when the alcohol goes into a flavour or fragrance
- Ventilate at low level, since the vapour is heavier than air
- Quote UN 1105 and HS 2905199090 on the shipping documents
- Order the mixture instead where the isomer identity does not matter and cost does
1-Pentanol FAQ
What is the amyl alcohol content?
99.80% minimum, with isoamyl alcohol at 0.10% maximum and n-valeraldehyde at 0.03% maximum.
What is the UN number and HS code?
UN number 1105 and HS code 2905199090. The EC number is 200-752-1.
What is the flash point?
