Description
Dichloromethane is an extra pure Ph.Eur. solvent with a minimum purity of 99,5 %, stabilised with amylene. It is identified by CAS number 75-09-2 and empirical formula CH₂Cl₂, with a molar mass of 84,93 g/mol and a density of 1,33 g/cm³. The boiling point is 40 °C, supporting rapid evaporation in extraction and work-up procedures. Common applications include liquid–liquid extraction, chromatography sample preparation and organic reaction media where a dense, low-boiling chlorinated solvent is specified. European substance identification is provided by EG nr. 200-838-9. Available from manufacturer Carl ROTH, the product suits environments that standardise on Ph.Eur. extra pure solvents. Defined purity, stabilisation and physical data help maintain consistent performance in validated and routine laboratory methods.

Questions about Dichloromethane, min. 99,5 %, Ph.Eur., extra pure, 1 l, glass
What is this article?
Dichloromethane, min. 99,5 %, Ph.Eur., extra pure, 1 l, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Technical & synthesis grade solvents, inside Solvents, in Lab chemicals.
Technical and synthesis grades are for cleaning, for a coarse extraction and for chemistry that does not end in a chromatogram. They cost less because more impurity is allowed. They are the wrong bottle to make a mobile phase or a volumetric standard.
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 Technical & synthesis grade solvents. The catalogue is Lab chemicals.
Shelves beside this one are Analytical grade solvents (p.a.), HPLC & LC-MS grade solvents, Dry & deuterated solvents (NMR, synthesis) and Green & alternative solvents.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
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.
