Description
Methylamine, 40 % in water, for synthesis is a ready aqueous amine reagent for organic preparation work in the research laboratory. Identified by CAS number 74-89-5 and empirical formula CH₅N, it has a molar mass of 31,06 g/mol, a density of 0,9 g/cm³, a boiling point of 48 °C and a flash point of −18 °C. The solution is EG number 200-820-0 and UN number 1235 support correct identification in chemical inventories and transport documentation. This grade from manufacturer Carl ROTH is intended for synthetic applications where a 40 % aqueous methylamine solution is specified as a building block or reactant. Handle according to standard laboratory practice for flammable and reactive amine solutions, and consult the accompanying safety documentation before use. Practical for method development, intermediate formation and general synthesis workflows needing a defined aqueous methylamine concentration in glass packaging.

Questions about Methylamine, 40 % in water, for synthesis, 250 ml, glass
What is this article?
Methylamine, 40 % in water, for synthesis, 250 ml, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Organic building blocks & synthesis reagents, inside Organic chemicals & synthesis reagents, in Lab chemicals.
A building block is an organic molecule bought to become part of a larger one. The structure, the CAS number and the purity decide it. A 95 percent reagent and a 99.9 percent reagent of the same name leave different impurities in the product. The functional groups are the reason it was chosen.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
