Description
Acetonitrile ROTIPURAN® is a high-purity solvent graded min. 99,5 %, p.a., ACS for analytical laboratory use. Identified by CAS number 75-05-8 and empirical formula C₂H₃N, it offers a molar mass of 41,05 g/mol, density of 0,79 g/cm³, boiling point of 81,65 °C and flash point of 2 °C. This polar aprotic solvent is routinely applied in HPLC mobile phases, sample extraction, organic synthesis work-up and general wet-chemistry procedures that demand p.a./ACS quality. Clear physical constants aid method development, solvent exchange calculations and safety documentation. The combination of defined purity, ACS compliance and convenient litre packaging makes it a practical choice for chromatography laboratories, quality control and research environments requiring reliable acetonitrile.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about Acetonitrile ROTIPURAN®, min. 99,5 %, p.a., ACS, 1 l, glass
What is this article?
Acetonitrile ROTIPURAN®, min. 99,5 %, p.a., ACS, 1 l, 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.
