Description
4-Bromo-3,5-dimethoxybenzaldehyde is an aromatic aldehyde intermediate offered at a minimum purity of 95 % for synthetic and biochemical laboratory work. Identified by CAS number 31558-40-4 and the empirical formula C₉H₉BrO₃, it has a molar mass of 245,07 g/mol. The structure combines a reactive formyl group with two methoxy substituents and a bromine atom on the benzene ring, giving a versatile handle for further functionalisation in organic synthesis. Substituted benzaldehydes of this type are commonly applied in condensation chemistry, reductive aminations and metal-catalysed cross-coupling sequences. The reagent is available from manufacturer Carl ROTH and supports stoichiometric planning thanks to its clearly stated molecular weight and identity data. With defined purity and composition, 4-bromo-3,5-dimethoxybenzaldehyde provides a practical starting point for multi-step preparations that require controlled introduction of bromine and methoxy motifs on an aromatic aldehyde core under standard organic laboratory conditions.

Questions about 4-Bromo-3,5-dimethoxybenzaldehyde, min. 95 %, 25 g
What is this article?
4-Bromo-3,5-dimethoxybenzaldehyde, min. 95 %, 25 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.
