Description
n-Heptane ROTISOLV® Pestilyse® is a high-purity aliphatic solvent with a minimum assay of 99 %, CAS number 142-82-5 and empirical formula C₇H₁₆. Its molar mass is 100,20 g/mol, density ranges from 0,68 to 0,69 g/cm³, the boiling point lies between 98,2 and 98,4 °C, and the flash point is −4 °C. These defined physical data support reproducible use in analytical and chromatographic workflows. Packed as 2,5 l in glass, the grade is intended for gas chromatography solvent applications where consistent quality and low interference matter. The ROTISOLV® Pestilyse® specification from manufacturer Carl ROTH aligns with demanding GC sample preparation and related residue-oriented work. Laboratories can rely on the stated purity, boiling range and density when selecting an n-heptane solvent for GC methods and general laboratory solvent duties within chromatography suites. The clear hydrocarbon profile and documented EG number 205-563-8 complete the identity data needed for routine laboratory documentation and method setup.

Questions about n-Heptane, ROTISOLV®, min. 99 %, Pestilyse®, 2.5 l, glass
What is this article?
n-Heptane, ROTISOLV®, min. 99 %, Pestilyse®, 2.5 l, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in HPLC & LC-MS grade solvents, inside Solvents, in Lab chemicals.
HPLC grade limits the absorbance and the residue that would appear as peaks or baseline drift. LC-MS grade goes further on metal ions and on particles that would suppress a mass spectrum. A solvent that is only analytical grade is a false economy on an LC-MS system.
A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
Which category should I open next?
The category is Solvents. The sub-category is HPLC & LC-MS grade solvents. The catalogue is Lab chemicals.
Shelves beside this one are Analytical grade solvents (p.a.), Dry & deuterated solvents (NMR, synthesis), Technical & synthesis grade solvents and Green & alternative solvents.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
