Description

3-Bromo-5-Isopropoxyphenylboronic Acid is a high-purity boronic acid derivative, a crucial building block in modern synthetic organic chemistry. Its value lies in its dual functionality, where the boronic acid group enables efficient cross-coupling reactions, and the bromo and isopropoxy substituents provide versatile handles for further structural elaboration. This compound is primarily needed by researchers and process chemists in the pharmaceutical and agrochemical industries for the development of new active ingredients and advanced materials.

Application
