Description
m-Xylene, min. 98,5 %, for synthesis is an aromatic hydrocarbon solvent and intermediate for laboratory synthesis. It carries CAS number 108-38-3 and empirical formula C₈H₁₀, with a molar mass of 106,17 g/mol, density of 0,86 g/cm³, flash point of 27 °C and boiling point of 139,1 °C. The minimum purity of 98,5 % supports synthetic and process chemistry where the meta-isomer is specified. EG number 203-576-3 and UN number 1307 identify the substance for regulatory and transport documentation. Physical properties enable predictable boiling behaviour and handling in organic synthesis workflows. The one-litre glass presentation is practical for repeated dispensing in research and development laboratories requiring consistent m-xylene quality.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about m-Xylene, min. 98.5 %, for synthesis, 1 l, glass
What is this article?
m-Xylene, min. 98.5 %, for synthesis, 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.
