The landscape of modern chemical synthesis is continually shaped by the development and application of key building blocks. Among these, organoboron compounds, particularly boronate esters, have emerged as indispensable tools. 4-Hydroxyphenylboronic Acid Pinacol Ester (HPBE), identified by its CAS number 269409-70-3, is a prime example, playing a crucial role in facilitating complex organic transformations, most notably the Nobel Prize-winning Suzuki–Miyaura (SM) coupling reaction. For procurement managers and research scientists, understanding HPBE's properties and its availability from reliable manufacturers and suppliers is vital.

Understanding HPBE's Chemical Utility

HPBE is a white to tan crystalline powder, valued for its versatility. Its chemical structure, featuring a hydroxyphenyl group attached to a pinacol-protected boronate ester, grants it a desirable combination of stability and reactivity. This stability is a significant advantage, making it easier to handle, store, and integrate into various synthetic protocols without premature degradation. This ease of use is a primary reason why many chemists prefer to buy 4-Hydroxyphenylboronic Acid Pinacol Ester from reputable sources. We, as a dedicated manufacturer and supplier, focus on delivering this intermediate with the highest purity and consistency.

Suzuki Coupling and Beyond

The Suzuki coupling reaction is a powerful method for creating new carbon-carbon bonds, essential for building the complex molecular architectures found in pharmaceuticals, advanced materials, and agrochemicals. HPBE serves as an excellent organoboron coupling partner in this process. Its reliable performance in SM coupling reactions makes it a go-to reagent for constructing biaryl systems and other valuable organic frameworks. When sourcing, it's important to consider not just the price, but also the overall value proposition offered by a supplier, including technical support and supply chain reliability. For those looking to purchase this intermediate, understanding its applications ensures its strategic integration into R&D pipelines.

Key Applications Driving Demand

  • Pharmaceutical Development: HPBE is critical for synthesizing drug candidates, acting as a building block for molecules with phenolic functionalities.
  • Materials Science: Its use extends to creating novel organic electronic materials, polymers, and functional coatings, where precise molecular assembly is key.
  • Research and Development: Academic and industrial laboratories rely on HPBE for exploring new synthetic routes and developing diverse chemical libraries.
