Description
N,N-Dimethylformamide ROTIPURAN® is a high-purity polar aprotic solvent offered at min. 99,8 % p.a., ACS grade, with CAS number 68-12-2 and empirical formula C₃H₇NO. The molar mass is 73,10 g/mol, density 0,95 g/cm³, flash point 57,5 °C and boiling point 153 °C. From manufacturer Carl ROTH, the ROTIPURAN® line provides defined physical data that support method development and quality control. DMF dissolves a wide range of organic and inorganic compounds and is frequently chosen for peptide chemistry, polymer work and chromatographic applications. Identification via EG nr. 200-679-5 and UN number 2265 aids regulatory and logistics handling. Consistent assay and documented boiling and density values help laboratories maintain reproducible solvent performance in both routine analysis and research-scale reactions requiring a reliable p.a. grade medium.
This article belongs on Analytical grade solvents (p.a.), in Solvents.

Questions about N,N-Dimethylformamide, ROTIPURAN®, min. 99,8 %, p.a., ACS, 250 ml, glass
What is this article?
N,N-Dimethylformamide, ROTIPURAN®, min. 99,8 %, p.a., ACS, 250 ml, 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.
