Description
Cyclohexane is a high-purity cyclic hydrocarbon solvent offered as ROTISOLV® UV/IR-Grade with a minimum assay of 99,9 %. It is identified by CAS number 110-82-7 and empirical formula C₆H₁₂, with a molar mass of 84,16 g/mol and a density of 0,78 g/cm³. The boiling range is 80 to 81 °C and the flash point is −20 °C, parameters that guide safe laboratory use. This UV/IR-Grade material is intended for ultraviolet-visible and infrared spectroscopy, where a defined non-polar solvent with low spectral interference is required. Delivered in a 2,5 l glass bottle, it is suitable for sample preparation, rinsing and measurement in UV/Vis spectroscopy and related spectrometric methods. The product from manufacturer Carl ROTH carries EG number 203-806-2 and UN number 1145. Analytical groups benefit from the stated purity, density and boiling data when selecting cyclohexane for reproducible spectroscopic workflows and consistent solvent performance.

Questions about Cyclohexane, ROTISOLV®, min. 99,9 %, UV/IR-Grade, 2.5 l, glass
What is this article?
Cyclohexane, ROTISOLV®, min. 99,9 %, UV/IR-Grade, 2.5 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?
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.
