n-Hexane
Buy 95% High Purity, HPLC, Anhydrous Reagent and Preparative HPLC Grade n-Hexane, in Stock Now.
Buy n-hexane online in the purity your extraction or analytical method actually needs, with the price shown up front. 95% High Purity Grade covers general extraction and solvent work. HPLC Grade and Preparative HPLC are purified and tested for chromatography, at bench and larger preparative scale. Anhydrous Reagent Grade, held to 10 ppm water or less, is the one to reach for in moisture sensitive reactions.
Every product ships with its SDS and COA posted online, and sizes run from 500 mL bottles up to 55 gallon drums. n-Hexane needs to be taken seriously before you order: it's extremely flammable, and chronic exposure carries a real, well documented neurotoxicity risk, so it ships to businesses, labs and schools, never residential addresses. We've put together a full safety and hazards guide, linked below, that's worth reading before anyone on your team handles it.

About n-Hexane
C6H14, a straight chain alkane, no branching, no double bonds. At room temperature it's a thin, colorless, highly volatile liquid with a faint petroleum smell, and it evaporates fast, which is exactly why it's prized as an extraction solvent: it pulls oil out of seeds and then leaves almost cleanly, with a low boiling point around 69°C. What people buy as plain hexane is often a mixture of isomers, while n-hexane specifically is the straight chain form, and that distinction matters for one big reason: n-hexane is the isomer responsible for the compound's well known neurotoxicity. Your body metabolizes it into 2,5-hexanedione, which damages peripheral nerves over repeated exposure, something branched hexane isomers don't do to the same degree.
COMMON APPLICATIONS
Oilseed and vegetable oil extraction, where its low boiling point lets it be recovered and reused efficiently. Chromatography and HPLC mobile phase work, where it's one of the standard non-polar solvents. General extraction and purification in research and industrial labs. Cleaning and degreasing in some industrial processes. Reaction solvent in organic synthesis where a non-polar, low boiling medium is needed. And historically, a component in some adhesive and printing formulations, though safer alternatives have replaced it in a lot of consumer facing uses.
GRADES EXPLAINED
95% High Purity Grade is solid, general purpose purity for extraction and bench solvent work. HPLC Grade is purified and tested specifically to avoid noise and ghost peaks in chromatography runs, and Preparative HPLC Grade is the same purity profile scaled for larger preparative chromatography work. Anhydrous Reagent Grade takes water content down to 10 ppm or less, which matters for reactions that water would interfere with.

Frequently Asked Questions
Where can I buy n-hexane online?
Right here. We carry n-hexane in 95% High Purity, HPLC, Anhydrous Reagent and Preparative HPLC grades, from 500 mL bottles up to 55 gallon drums. Pick the grade and size, check the price, and order with no quote needed for standard sizes. Most in stock orders ship within 1 to 2 business days.
Is n-hexane dangerous to work with?
It needs real respect. n-Hexane is extremely flammable, with a flash point well below freezing, so ignition sources are a constant concern. The bigger long term risk is neurotoxicity: your body converts n-hexane into a metabolite called 2,5-hexanedione, which damages peripheral nerves with repeated exposure, sometimes permanently. Work in well ventilated areas, avoid skin contact, and read our full safety and hazards guide before handling it regularly.
What's the difference between hexane and n-hexane?
Hexane often refers to a mixed isomer solvent, while n-hexane is specifically the straight chain isomer. That distinction actually matters for safety, since n-hexane is the isomer responsible for the compound's documented neurotoxicity, while branched isomers don't carry the same risk to the same degree. All four products on this page are the n-hexane isomer specifically, not a mixed hexanes product.
95% High Purity or HPLC Grade, which do I need?
Depends on the job. If you're extracting oils or running general solvent work, 95% High Purity Grade does it at a lower price. If you're running chromatography or an analytical method, HPLC Grade is purified and tested to avoid the trace impurities that show up as noise or ghost peaks. Preparative HPLC Grade is the same purity, just scaled up for bigger preparative runs.
Is any of your n-hexane Kosher, Halal or food grade?
No. None of the four n-hexane products on this page carry Kosher, Halal or food grade certification. They're sold for laboratory, analytical and industrial use. Each product does have an SDS and lot specific COA on its page, so you can confirm the exact specs before ordering.
What is n-hexane actually used for?
Mostly extraction and chromatography. It's the standard solvent for pulling oil out of seeds like soybean and canola, since it evaporates cleanly and can be recovered and reused. It's also one of the common non-polar solvents in HPLC mobile phase work and general lab extraction. Given its neurotoxicity profile, every application should go through a proper risk assessment, especially for repeated or prolonged exposure.
Can I buy n-hexane in bulk?
Yes. 95% High Purity Grade scales up through 5 gallon pails and 55 gallon drums right on the product page. For pallets or a recurring delivery schedule, request pricing through Bulk & Custom Chemicals. Autoship takes 10% off eligible repeat orders.
How should n-hexane be stored?
Keep it tightly sealed in its original container, in a cool, dry, well ventilated area completely away from heat, sparks and open flames, since it's extremely flammable with a flash point below freezing. Store it away from strong oxidizers, strong acids and bases. Our How to Store n-Hexane guide covers containers, grounding and bonding, and incompatibilities in full detail.
