Heptane
Buy n-Heptane in Lab, 99% High Purity, HPLC and Anhydrous Reagent Grade, in Stock Now.
Buy n-heptane online in the grade your method calls for, with the price on the page and no quote to wait on. It's a short, focused list here. Lab Grade and 99% High Purity Grade cover general solvent work and octane rating standards. HPLC Grade and Preparative HPLC are built for chromatography, and Anhydrous Reagent Grade, tested to 10 ppm water or less, is the one to reach for when moisture in your heptane would throw off a sensitive reaction.
Every product ships with its SDS and COA posted online, and sizes run from 500 mL bottles up to 55 gallon drums, with 4 packs and cases on several grades. n-Heptane is flammable and classed as an aquatic hazard, so it ships to businesses, labs and schools rather than residential addresses, and it's not certified Kosher, Halal or food grade on any of the five products here.

About Heptane
C7H16, seven carbons in a straight chain, no branching, no double bonds. That's n-heptane. At room temperature it's a thin, colorless liquid with the kind of petroleum smell you half expect from something related to gasoline, since heptane is actually a real component of it. It melts around -91°C and boils at about 98.3°C, so it stays liquid across almost any lab or warehouse condition you'd run into. One number worth knowing if you're in fuel testing: n-heptane is the zero point on the octane rating scale, the reference fuel that detonates most easily under compression, with isooctane sitting at 100 on the other end.
COMMON APPLICATIONS
Non-polar extraction and sample prep, HPLC and chromatography mobile phase work, octane rating reference fuel for engine testing, rubber vulcanization and rubber cement manufacturing, adhesive and ink removal, and general cleaning and degreasing wherever a non-polar, moderately volatile solvent is needed.
GRADES EXPLAINED
Lab Grade is a mixed isomer product, n-heptane along with some iso-heptane, and it's the economical choice for general solvent use, cleaning and sample prep where isomer purity doesn't matter. 99% High Purity Grade strips out those other isomers for work that needs a cleaner, more consistent n-heptane. HPLC and Preparative HPLC Grade are purified and tested specifically for chromatography, where trace impurities can show up as ghost peaks. Anhydrous Reagent Grade takes purity further still, holding water content to 10 ppm or less, which matters for moisture sensitive reactions and certain analytical methods.

Frequently Asked Questions
Where can I buy heptane online?
Right here. We carry n-heptane in Lab, 99% High Purity, HPLC, Preparative HPLC and Anhydrous Reagent Grade, 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.
Lab Grade or 99% High Purity, which heptane do I actually need?
Depends on whether isomer purity matters to your work. Lab Grade is a mixed isomer product, n-heptane along with some iso-heptane, and it's fine for general cleaning, sample prep and non-polar extraction. The 99% High Purity Grade strips those other isomers out, which matters for octane reference work or anywhere a consistent, single isomer heptane changes your results.
What's the point of HPLC Grade heptane over Lab Grade?
Trace impurities. HPLC Grade heptane is purified and tested specifically so it won't introduce ghost peaks or baseline noise into a chromatography run, which Lab Grade isn't held to. If you're running mobile phase or extraction work on an HPLC system, that difference actually shows up in your data. For cleaning or bulk solvent use, Lab Grade is the more economical pick and works just fine.
Is heptane the same as hexane?
No, though they get used interchangeably more often than they should. Heptane has seven carbons, hexane has six, and that one carbon changes the boiling point, evaporation rate and in some cases the safety profile. Heptane is actually the preferred replacement for hexane in a lot of extraction protocols these days, since hexane carries more documented neurotoxicity concerns. Check your specific method before swapping one for the other.
Do I need a permit, and can heptane ship to a home address?
No purchase permit is required. Heptane does ship as a flammable liquid with aquatic hazard classifications, though, so it's restricted to business, lab or school delivery addresses rather than residential ones. Each product page lists its specific shipping details, and Customer Care at 512-668-9918 can confirm before you order if you're not sure your address qualifies.
Is any of your heptane Kosher, Halal or food grade?
No. None of the five heptane products on this page carry Kosher, Halal or food grade certification. They're sold for laboratory, analytical and industrial use. Each one does come with an SDS and lot specific COA on its product page, so you can confirm the exact specs before ordering.
What is heptane actually used for?
A lot of things, honestly. It's a go to non-polar solvent for extraction and sample prep, a mobile phase component in HPLC work, the zero reference point on the octane rating scale used in fuel testing, and an ingredient in rubber cement and ink manufacturing. It also shows up as an adhesive remover and general degreaser. Whatever the application, the SDS is worth a look before using it outside a standard lab setting.
Can I buy heptane in bulk?
Yes. Lab Grade and 99% High Purity heptane both scale up through 5 gallon pails, 20 liter containers 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 heptane be stored?
Keep it tightly sealed in its original container, in a cool, well ventilated area away from heat, sparks and open flames, since it's a Category 2 flammable liquid. Store it away from strong oxidizers. Heptane also carries an aquatic hazard rating, so keep spills contained and out of drains. The Chemical Storage Compatibility Chart is worth a check if you're storing it near other solvents or oxidizing chemicals.
