Description
Isooctane is a branched alkane solvent offered as ROTISOLV® grade with a minimum assay of 99,5 % for GC-MS use. It is identified by CAS number 540-84-1 and empirical formula C₈H₁₈, with 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, supporting controlled use in analytical laboratories. This high-purity grade is intended for gas chromatography applications that need low background and stable solvent performance, including sample preparation, dilution, and related GC-MS steps. Physical and chemical parameters correspond to established reference data for isooctane, assisting method transfer and day-to-day chromatographic practice. The solvent is available from manufacturer Carl ROTH within the ROTISOLV® GC-MS range and suits laboratories performing residue testing, calibration work, and quality-control analyses that call for a defined isooctane grade.
This article is part of Chromatography standards (GC, HPLC, pesticides), in Analytical standards & reference materials.

Questions about Isooctane, ROTISOLV® min. 99,5 %, GC-MS, 1 l, glass
What is this article?
Isooctane, ROTISOLV® min. 99,5 %, GC-MS, 1 l, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Chromatography standards (GC, HPLC, pesticides), inside Analytical standards & reference materials, in Lab chemicals.
A chromatography standard is the substance, or the mix, injected so a peak can be named and quantified. Pesticide mixes, residual-solvent mixes and single-compound standards are different articles. The concentration and the solvent are the specification. The solvent has to be one the method may contain.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
