Description
Hexane (Isomers) for synthesis is a hydrocarbon solvent grade specified with less than 5 % n-hexane for synthetic and preparative laboratory use. The isomer mixture has the empirical formula C₆H₁₄ and a molar mass of 86,18 g/mol, with a density of 0,669 g/cm³, a boiling range of 58 to 62 °C and a flash point below −29 °C. These physical data support predictable evaporation and phase behaviour in organic reaction media, extractions and process steps where a controlled n-hexane content is required. EG number 931-254-9 identifies the substance for documentation and regulatory workflows. Chemists employ hexane isomer blends as solvents and work-up media when low n-hexane composition is specified relative to the broader C₆ fraction. The defined boiling window and low density aid handling during concentration, washing and non-polar extraction sequences in research and development settings.

Questions about Hexane (Isomers), for synthesis, <5 % n-hexane, 500 ml, glass
What is this article?
Hexane (Isomers), for synthesis, <5 % n-hexane, 500 ml, 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?
