Description
Dichloromethane is a high-purity laboratory solvent offered as ROTISOLV® min. 99,8 %, UV/IR-Grade and stabilised with amylene. With CAS number 75-09-2 and empirical formula CH₂Cl₂, it has a molar mass of 84,93 g/mol and a density of 1,33 g/cm³. The boiling point is 40 °C, which supports rapid solvent removal in sample work-up and analytical preparation. This 2,5 l glass pack is intended for ultraviolet-visible and infrared spectroscopy applications that demand low UV/IR background and a defined minimum assay. Dichloromethane is commonly used as an extraction and process solvent in UV/Vis spectroscopy and broader spectrometry workflows. Amylene stabilisation helps preserve quality during normal laboratory storage and handling. Available from manufacturer Carl ROTH in the ROTISOLV® UV/IR-Grade line, it serves analytical chemistry laboratories that require reproducible solvent performance for dilution, extraction, and instrumental measurement protocols.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about Dichloromethane, ROTISOLV®, min. 99,8 %, UV/IR-Grade, 2.5 l, glass
What is this article?
Dichloromethane, ROTISOLV®, min. 99,8 %, UV/IR-Grade, 2.5 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?
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.
