5-Bromopentylboronic acid
5-Bromopentylboronic acid (CAS: 120986-85-8), with the empirical formula C5H12BBrO2 and a molecular weight of 194.86 g/mol, is an organoboron compound utilised in organic synthesis. This reagent is often employed as a building block in cross-coupling reactions and for the introduction of functionalised alkyl chains into more complex molecules. It is typically supplied with an assay of ≥94% and may contain varying amounts of anhydride.
Organic Synthesis Building Block
5-Bromopentylboronic acid serves as a versatile intermediate in the construction of carbon-carbon bonds through reactions such as Suzuki-Miyaura cross-coupling. Its bifunctional nature allows for subsequent modifications or integrations into diverse molecular frameworks.
Functionalised Alkyl Chain Introduction
This boronic acid derivative is valuable for appending a five-carbon chain, terminated with a bromine atom, to target molecules. The bromine can then participate in further synthetic transformations, offering a route to more elaborate chemical structures.
Reagent in Organometallic Chemistry
As an organometallic reagent, it participates in various metal-catalysed reactions, enabling the synthesis of complex organic compounds. Its specific structure makes it suitable for applications requiring the installation of a bromo-functionalised pentyl group.
