Description
5-Formyl-2-thiopheneboronic acid is a heterocyclic boronic acid building block supplied at a minimum purity of 95 % for synthetic and biochemical laboratory work. It is registered under CAS number 4347-33-5, with the empirical formula C₅H₅BO₃S and a molar mass of 155,97 g/mol. The formyl-substituted thiophene scaffold combined with the boronic acid function makes the reagent relevant for cross-coupling chemistry, intermediate preparation, and structure–activity studies in research settings. This grade is Clear identity data support stoichiometric planning and quality documentation in regulated or academic environments. The material belongs to the chemicals and biochemicals offering from manufacturer Carl ROTH and is intended for professional laboratory use. Laboratories should apply standard handling practice for organoboron reagents and verify compatibility with their catalytic or coupling protocols. Consistent molecular parameters help ensure reproducible results across synthetic campaigns and method development projects.

Questions about 5-Formyl-2-thiopheneboronic acid, min. 95 %, 2 g
What is this article?
5-Formyl-2-thiopheneboronic acid, min. 95 %, 2 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.
