Description
Isooctane is a high-purity hydrocarbon solvent supplied as ROTISOLV® HPLC grade with a minimum assay of 99,9 %, intended for demanding liquid chromatography and related analytical work. Identified by CAS number 540-84-1 and empirical formula C₈H₁₈, it has a molar mass of 114,23 g/mol and a density of 0,69 g/cm³. The boiling point is 99,2 °C and the flash point is −12 °C, so appropriate handling of this flammable liquid is essential in the laboratory. This grade is offered in a 2,5 l glass bottle, supporting routine HPLC mobile-phase preparation, sample work-up and environmental analysis workflows where low background and consistent solvent quality matter. Physical and identity data align with EG number 208-759-1. Isooctane from manufacturer Carl ROTH is positioned for chromatography and liquid-chromatography applications that benefit from a defined HPLC-grade alkane solvent. Use standard laboratory practice for storage, dispensing and waste disposal of volatile organic solvents.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about Isooctane, ROTISOLV® HPLC min. 99,9 %, 2.5 l, glass
What is this article?
Isooctane, ROTISOLV® HPLC min. 99,9 %, 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?
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.
