Description
Benzene ROTIPURAN® is a high-purity aromatic solvent for analysis, offered at minimum 99,5 % p.a. grade for demanding laboratory applications. It is registered under CAS number 71-43-2 and EG nr. 200-753-7, with empirical formula C₆H₆, molar mass 78,11 g/mol, density 0,876 g/cm³, flash point −11 °C, and boiling point 80,09 °C. Physical constants and assay data help laboratories document reagent identity for quality systems and method files. This benzene grade from manufacturer Carl ROTH belongs to the ROTIPURAN® solvents-for-analysis line and is intended for trained users who manage flammable aromatic hydrocarbons under appropriate controls. Pack size, purity, and CAS labelling facilitate inventory selection and alignment with existing analytical procedures without unnecessary reformulation.

Questions about Benzene ROTIPURAN®, min. 99.5 %, p.a., 1 l, glass
What is this article?
Benzene ROTIPURAN®, min. 99.5 %, p.a., 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.
