Beschreibung
Formamide is a high-purity analytical solvent with a minimum assay of 99,5 %, specified p.a. and ACS grade, CAS number 75-12-7 and empirical formula CH₃NO. With a molar mass of 45,04 g/mol, density of 1,13 g/cm³, boiling point of 218,3 °C and flash point of 152 °C, it offers well-defined physical properties for demanding laboratory work. Formamide from manufacturer Carl ROTH is widely used in nucleic-acid workflows, organic synthesis support and general wet-chemistry procedures that require a polar, high-boiling amide solvent. The p.a./ACS classification supports routine and research use in solvents for analysis. Clear identity data including EG nr. 200-842-0 help laboratories maintain traceable inventory and method documentation. This pack size balances convenient handling with sufficient volume for repeated analytical series in chemical and life-science laboratories.
This article belongs on Analytical grade solvents (p.a.), in Solvents.

Questions about Formamide, min. 99,5 %, p.a., ACS, 500 ml, glass
What is this article?
Formamide, min. 99,5 %, p.a., ACS, 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 Labor- und Industriechemikalien.
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 Labor- und Industriechemikalien.
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.
