Beschrijving
N,N-Dimethylacetamide ROTISOLV® is a high-purity solvent supplied at min. 99,99 % for headspace-grade chromatographic work. With CAS number 127-19-5 and empirical formula C₄H₉NO, it offers a molar mass of 87,12 g/mol and a density of 0,94 g/cm³. The boiling point is 166 °C and the flash point is 64 °C, supporting controlled handling in analytical laboratories. Packaged as 1 l in glass, this ROTISOLV® grade solvent is intended for gas-chromatographic and headspace applications where low background interference is essential. Physical data and identity parameters from manufacturer Carl ROTH align with routine solvent selection for GC workflows. The material is suited to sample preparation and chromatographic methods that demand consistent purity and defined thermal properties. Laboratories working with residual-solvent analysis or sensitive headspace techniques can integrate this solvent into established protocols while relying on the stated specification profile.
This article is part of HPLC & LC-MS grade solvents, in Solvents. See also Analytical grade solvents (p.a.).

Questions about N,N-Dimethylacetamide ROTISOLV®, min. 99,99 %, Headspace Grade, 1 l, glass
What is this article?
N,N-Dimethylacetamide ROTISOLV®, min. 99,99 %, Headspace Grade, 1 l, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in HPLC & LC-MS grade solvents, inside Solvents, in Chemicaliën.
HPLC grade limits the absorbance and the residue that would appear as peaks or baseline drift. LC-MS grade goes further on metal ions and on particles that would suppress a mass spectrum. A solvent that is only analytical grade is a false economy on an LC-MS system.
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 HPLC & LC-MS grade solvents. The catalogue is Chemicaliën.
Shelves beside this one are Analytical grade solvents (p.a.), 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.
