Description
Cyclohexane ROTIPURAN® is an analytical-grade aliphatic solvent supplied at min. 99,5 % purity and conforming to p.a., ACS and ISO requirements. It is identified by CAS 110-82-7 and EG nr. 203-806-2, with empirical formula C₆H₁₂, molar mass 84,16 g/mol and density 0,78 g/cm³. The boiling range is 80 to 81 °C and the flash point is −20 °C, so appropriate flammable-liquid handling is essential. This grade is intended for laboratory extraction, chromatography sample work-up, cleaning and general analytical solvent applications where a defined high-purity cyclohexane is specified. Documented identity, density and thermal data support safe storage planning and consistent performance in quantitative and qualitative workflows across chemical analysis laboratories.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about Cyclohexane, ROTIPURAN®, min. 99,5 %, p.a., ACS, ISO, 1 l, glass
What is this article?
Cyclohexane, ROTIPURAN®, min. 99,5 %, p.a., ACS, ISO, 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?
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.
