Description
Acetonitrile ROTISOLV® HPLC, minimum 99,9 %, is a high-purity polar aprotic solvent for liquid chromatography, specified under CAS number 75-05-8 with empirical formula C₂H₃N. Molar mass is 41,05 g/mol and density is 0,79 g/cm³. The boiling point is 81,65 °C and the flash point is 2 °C, requiring careful handling as a flammable laboratory solvent. EG number 200-835-2 and UN number 1648 support compliant labelling and logistics. Laboratories select acetonitrile of this purity when low UV background and consistent chromatographic performance are needed. The combination of defined physical data and HPLC-oriented specification makes it a standard choice for routine and method-development liquid chromatography work.
This article is part of HPLC & LC-MS grade solvents, in Solvents. See also Analytical grade solvents (p.a.).

Questions about Acetonitrile ROTISOLV® HPLC, min. 99,9 %, 1 l, glass
What is this article?
Acetonitrile ROTISOLV® HPLC, min. 99,9 %, 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.
