Description
Acetonitrile with 0.1 % trifluoroacetic is a ROTISOLV® LC-MS-Grade solvent blend at minimum 99,9 % purity, intended for chromatographic applications that require a strong acidic eluent additive. The acetonitrile base (empirical formula C₂H₃N) presents a molar mass of 41,05 g/mol and a density of 0,79 g/cm³, with a boiling point of 81,65 °C and a flash point of 12,8 °C (UN number 1648). Pre-blended trifluoroacetic modifier supports sharp peak shapes and reproducible retention in reversed-phase LC-MS workflows, reducing the need for manual acid dosing at the bench. The product is Offered by manufacturer Carl ROTH in the ROTISOLV® solvents-with-eluent-additives range, it provides a defined LC-MS-grade matrix for laboratories working with peptide, small-molecule and related separations under acidic mobile-phase conditions.
This article belongs on Technical & synthesis grade solvents, in Solvents.

Questions about Acetonitrile with 0.1 % Trifluoroacetic, ROTISOLV® min. 99,9 %, LC-MS-Grade, 1 l
What is this article?
Acetonitrile with 0.1 % Trifluoroacetic, ROTISOLV® min. 99,9 %, LC-MS-Grade, 1 l is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Technical & synthesis grade solvents, inside Solvents, in Lab chemicals.
Technical and synthesis grades are for cleaning, for a coarse extraction and for chemistry that does not end in a chromatogram. They cost less because more impurity is allowed. They are the wrong bottle to make a mobile phase or a volumetric standard.
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 Technical & synthesis grade solvents. The catalogue is Lab chemicals.
