Description
5-Bromo-1-chloroisoquinoline is a halogenated heterocyclic building block with the empirical formula C₉H₅BrClN, a molar mass of 242,5 g/mol and CAS number 34551-41-2. The dual halogenation supports sequential cross-coupling, nucleophilic aromatic substitution and further ring functionalisation when constructing more elaborate scaffolds. Laboratories use the material as an intermediate for pharmaceutical research, agrochemical exploration and method development around nitrogen heterocycles. Physical data from manufacturer Carl ROTH centre on the stated molar mass, enabling accurate stoichiometric calculations in multi-step sequences. quantity suits both exploratory synthesis and scale-up of intermediate campaigns. As a biochemical-grade chemical reagent it fits standard laboratory workflows for heterocyclic chemistry without requiring specialised handling beyond ordinary good laboratory practice for halogenated aromatics. Clear identity data (CAS, formula and molar mass) facilitate documentation, inventory control and regulatory classification in research and development environments.

Questions about 5-Bromo-1-chloroisoquinoline, 50 g
What is this article?
5-Bromo-1-chloroisoquinoline, 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.
