Description
Acetonitrile ROTIDRY®Sept is a high-purity dry solvent grade specified at ≥ 99,9 % with water content ≤ 50 ppm H₂O, filled in a 250 ml septum bottle for moisture-sensitive work. It is registered under CAS number 75-05-8 and EG number 200-835-2, with empirical formula C₂H₃N and molar mass 41,05 g/mol. Key physical data include a density of 0,79 g/cm³, a flash point of 2 °C and a boiling point of 81,65 °C, which are relevant for solvent selection, evaporation control and safety planning. The septum packaging supports repeated sampling while limiting atmospheric moisture uptake in anhydrous synthesis, sample preparation and instrumental methods. Material from manufacturer Carl ROTH in the ROTIDRY®Sept range is suited to laboratories that need low-water acetonitrile for chromatography, organic reactions and analytical protocols. UN number 1648 applies for transport. Documented purity, water limit and physicochemical parameters help ensure consistent specification against method requirements without additional performance claims beyond the stated grade.
This article belongs on Dry & deuterated solvents (NMR, synthesis), in Solvents.

Questions about Acetonitrile, ROTIDRY®Sept >= 99,9 % (<= 50 ppm H2O), 250 ml, septum bottle
What is this article?
Acetonitrile, ROTIDRY®Sept >= 99,9 % (<= 50 ppm H2O), 250 ml, septum bottle is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Dry & deuterated solvents (NMR, synthesis), inside Solvents, in Lab chemicals.
A dry solvent has had water removed to a stated level, for a reaction that water would stop. A deuterated solvent replaces hydrogen with deuterium so an NMR spectrum is not drowned by the solvent signal. The isotopic enrichment and the water content are the two specifications. Caps and septa matter, because either product picks up moisture from the air.
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.
