Description
Acetonitrile ROTISOLV® is a high-purity solvent with a minimum assay of 99,8 %, intended for preparative HPLC and related chromatographic work. It has the empirical formula C₂H₃N, molar mass 41,05 g/mol, CAS number 75-05-8 and EG number 200-835-2. Key physical data include a density of 0,79 g/cm³, flash point of 2 °C and boiling point of 81,65 °C, which support method setup, solvent handling and process safety planning. This ROTISOLV® grade from manufacturer Carl ROTH is positioned specifically for preparative HPLC, giving chromatographers a clearly specified acetonitrile option when purity and application fit are essential. The combination of assay, molecular identity and documented physical constants helps laboratories maintain reproducible preparative methods while managing flammable solvent practices appropriately in routine analytical and preparative environments.
This article is part of HPLC & LC-MS grade solvents, in Solvents. See also Analytical grade solvents (p.a.).

Questions about Acetonitrile ROTISOLV®, min. 99,8 %, for preparative HPLC, 2.5 l, glass
What is this article?
Acetonitrile ROTISOLV®, min. 99,8 %, for preparative HPLC, 2.5 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 Lab chemicals.
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 Lab chemicals.
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?
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.
