Description
Formic acid ROTIPURAN® min. 85 %, p.a., is an analytical-grade carboxylic acid for laboratory reagents and reference work, identified by CAS number 64-18-6 and the empirical formula CH₂O₂. It has a molar mass of 46,02 g/mol, a density of 1,19 g/cm³, a boiling point of 106 °C, and a flash point of 65 °C, giving a clear physical profile for handling and method setup. The product is a. quality. ROTIPURAN® branding denotes the manufacturer’s analytical line; the material comes from manufacturer Carl ROTH for routine and specialised analytical use. Laboratories employ it in sample preparation, mobile-phase or reagent formulation, and procedures where a defined minimum 85 % formic acid content is required. EG number 200-579-1 supports regulatory and catalogue cross-checks. The combination of stated purity grade, pack size, and physicochemical data allows straightforward integration into existing analytical protocols without extending beyond the manufacturer’s published specifications.

Questions about Formic acid, ROTIPURAN® min. 85 %, p.a., 500 ml, glass
What is this article?
Formic acid, ROTIPURAN® min. 85 %, p.a., 500 ml, 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 Produits chimiques de laboratoire et industriels.
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 Produits chimiques de laboratoire et industriels.
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.
