Description
n-Heptane, min. 99.75 %, for synthesis is an aliphatic hydrocarbon solvent supplied for synthetic chemistry and related laboratory work. It carries CAS number 142-82-5, empirical formula C₇H₁₆ and EG nr. 205-563-8, with a molar mass of 100,20 g/mol. Physical data include a density of 0,68 to 0,69 g/cm³, flash point of −4 °C and boiling range of 98,2 to 98,4 °C, supporting predictable handling in controlled synthesis setups. This grade is filled as 500 ml in glass and is offered from manufacturer Carl ROTH for laboratories that specify n-heptane at minimum 99.75 % purity for preparative and general synthetic applications. Typical uses include non-polar extraction media, reaction solvents and process steps where a defined C₇ alkane cut is required. The glass pack size suits bench-scale work and reagent cabinets that prefer smaller volumes. Always observe flammable-liquid precautions consistent with the stated flash point and boiling range when transferring or storing the solvent in the laboratory.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about n-Heptane, min. 99.75 %, for synthesis, 500 ml
What is this article?
n-Heptane, min. 99.75 %, for synthesis, 500 ml is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Solvants de qualité analytique (p.a.), inside Solvants, in Produits chimiques.
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 Solvants. The sub-category is Solvants de qualité analytique (p.a.). The catalogue is Produits chimiques.
Shelves beside this one are Solvants de qualité HPLC & LC-MS, Solvants secs & deutérés (NMR, synthèse), Solvants de qualité technique & synthèse and Solvants verts & alternatifs.
What should I check before I order?
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.
