Description
5-Bromothiophene-2-carboxylic acid methyl ester is a brominated heterocyclic ester used as a versatile intermediate in organic and medicinal chemistry. The compound has the empirical formula C₆H₅BrO₂S, a molar mass of 221,07 g/mol and CAS number 62224-19-5. Its thiophene core bearing both a bromine substituent and a methyl ester group enables diverse transformations, including metal-catalysed couplings, ester hydrolysis and further functionalisation of the heteroaromatic ring. Physical parameters include a flash point of 106,1 °C and a boiling point of 251,9 °C, useful for process and safety evaluation. The 50 g pack size supports extended synthetic campaigns and intermediate stock preparation. Data from manufacturer Carl ROTH cover molar mass and thermal properties for reliable stoichiometric and handling decisions. Classified among biochemicals and fine chemicals, this reagent is intended for laboratory use by trained staff under standard chemical-safety practices in research and development settings.

Questions about 5-Bromothiophene-2-carboxylic acid methy, l ester, 50 g
What is this article?
5-Bromothiophene-2-carboxylic acid methy, l ester, 50 g 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.
