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.

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 Technical & synthesis grade solvents, inside Solvents, in Lab chemicals.
Technical and synthesis grades are for cleaning, for a coarse extraction and for chemistry that does not end in a chromatogram. They cost less because more impurity is allowed. They are the wrong bottle to make a mobile phase or a volumetric standard.
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 Technical & synthesis grade solvents. The catalogue is Lab chemicals.
Shelves beside this one are Analytical grade solvents (p.a.), HPLC & LC-MS grade solvents, Dry & deuterated solvents (NMR, synthesis) and Green & alternative solvents.
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.
