Description
Trichloromethane/Chloroform ROTIPURAN® is an analytical-grade solvent with a minimum purity of 99 % (p.a.), stabilised with ethanol for laboratory use. The compound carries CAS number 67-66-3, EG number 200-663-8 and the empirical formula CHCl₃, with a molar mass of 119,38 g/mol. Physical data include a density of 1,48 g/cm³ and a boiling point of 61 °C. Available from manufacturer Carl ROTH, the product is positioned among solvents for analysis (p.a.) and is widely applied in organic synthesis work-up, analytical chemistry and teaching laboratories. Stabilisation with ethanol helps maintain integrity under normal storage and handling conditions in the laboratory. Users should observe standard precautions for chlorinated solvents and consult the accompanying safety documentation before use. The combination of defined purity, known physical constants and convenient one-litre packaging makes this chloroform grade a practical choice for routine analytical workflows.

Questions about Trichloromethane/Chloroform, ROTIPURAN®, min. 99 %, p.a., 1 l, glass
What is this article?
Trichloromethane/Chloroform, ROTIPURAN®, min. 99 %, 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?
