Description
n-Heptane is a straight-chain aliphatic hydrocarbon supplied at min. 99 % purity for synthesis applications. Identified by CAS number 142-82-5 and empirical formula C₇H₁₆, it has a molar mass of 100,20 g/mol and a density of 0,68 to 0,69 g/cm³. The boiling range is 98,2 to 98,4 °C, with a flash point of −4 °C, underscoring its high volatility and the need for controlled handling in the laboratory. This grade is intended for synthetic work where a defined non-polar solvent or intermediate is required. Physical data support its use in extractions, reaction media, and process chemistry under appropriate safety measures. The material is With EG number 205-563-8 and UN number 1206, the product is clearly characterised for laboratory inventory and regulatory documentation. Consistent purity and well-documented physicochemical properties make this n-heptane a reliable choice for synthesis workflows that demand a high-assay C₇ alkane solvent.

Questions about n-Heptane, min. 99 %, for synthesis, 1 l, glass
What is this article?
n-Heptane, min. 99 %, for synthesis, 1 l, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Analytical grade solvents (p.a.), inside Solvents, in Lab chemicals.
An analytical-grade solvent, often marked p.a., has impurity limits tight enough for classical analysis and for preparing reagents. It is not automatically low enough in UV absorbance for HPLC, and it is not dry enough for a water-sensitive reaction. The grade is the purchase.
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 Analytical grade solvents (p.a.). The catalogue is Lab chemicals.
Shelves beside this one are HPLC & LC-MS grade solvents, Dry & deuterated solvents (NMR, synthesis), Technical & synthesis grade solvents and Green & alternative solvents.
What should I check before I order?
