Description
Acetonitrile ROTISOLV® is an LC-MS-Grade solvent with a minimum purity of 99,95 %, formulated for high-sensitivity liquid chromatography–mass spectrometry. It carries CAS number 75-05-8 and the empirical formula C₂H₃N, with a molar mass of 41,05 g/mol and a density of 0,79 g/cm³. Boiling point is 81,65 °C and flash point is 2 °C, giving clear physical reference points for laboratory handling and storage planning. The EG number 200-835-2 identifies the substance under European chemical inventory rules. Analytical laboratories rely on ROTISOLV® LC-MS acetonitrile when peak shape, baseline stability and mass-spectrometric cleanliness must be maintained across routine and research methods. Consistent solvent quality helps protect columns, detectors and long-term method robustness in chromatographic applications.
This article is part of HPLC & LC-MS grade solvents, in Solvents. See also Analytical grade solvents (p.a.).

Questions about Acetonitrile ROTISOLV®, min. 99,95 %, LC-MS-Grade, 1 l, glass
What is this article?
Acetonitrile ROTISOLV®, min. 99,95 %, LC-MS-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 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.
