Description
Formic acid ROTIPURAN® min. 99 %, LC-MS Grade is a high-purity laboratory reagent with CAS number 64-18-6 and empirical formula CH₂O₂. It has a molar mass of 46,02 g/mol and a density of 1,22 g/cm³, with a boiling point of 101 °C and a flash point of 49 °C. Formic acid is routinely applied for mobile-phase acidification, peptide and small-molecule sample preparation, and sensitive detection methods in pharmaceutical, environmental, and biochemical laboratories. The product is available from manufacturer Carl ROTH under the ROTIPURAN® LC-MS Grade line and is identified by EG number 200-579-1. Physical constants such as density and boiling behaviour support reproducible handling, method transfer, and documentation in regulated or research settings. The compact glass presentation suits method development, reference analyses, and routine LC-MS work where controlled, high-purity formic acid is essential for consistent chromatographic performance.

Questions about Formic acid, ROTIPURAN® min. 99 %, LC-MS Grade, 10 ml, glass ampoule
What is this article?
Formic acid, ROTIPURAN® min. 99 %, LC-MS Grade, 10 ml, glass ampoule 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?
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.
