Chemical intermediates are the unsung heroes of the chemical industry, forming the crucial building blocks that bridge raw materials and finished products. Their synthesis, purification, and reliable supply are fundamental to the success of countless manufacturing processes. Among the vast array of such compounds, 4-Hydroxyphenylboronic Acid (CAS 71597-85-8) exemplifies the importance and versatility of a key chemical intermediate.

At its core, 4-Hydroxyphenylboronic Acid is a fine chemical intermediate primarily utilized in the production of more complex molecules. Its unique structure, featuring a phenyl ring substituted with both a hydroxyl (-OH) group and a boronic acid [-B(OH)2] group, makes it exceptionally valuable in organic synthesis. The boronic acid functional group is particularly renowned for its participation in palladium-catalyzed cross-coupling reactions, most notably the Suzuki-Miyaura coupling, a vital tool for forming carbon-carbon bonds.

The applications of 4-Hydroxyphenylboronic Acid span across several high-value sectors. In the pharmaceutical industry, it serves as a precursor for synthesizing active pharmaceutical ingredients (APIs), where precise molecular construction is paramount. In the electronics sector, it is an important intermediate for OLED (Organic Light-Emitting Diode) materials, contributing to the development of advanced display technologies. Its utility also extends to other areas of fine chemical synthesis and materials science.

For procurement managers and R&D scientists, understanding the specifications of intermediates like 4-Hydroxyphenylboronic Acid is critical. Typically supplied as an off-white to light brown powder with an assay of ≥98.0%, its purity directly influences the efficiency and outcome of subsequent reactions. When you need to buy such materials, seeking out manufacturers with stringent quality control and transparent documentation, such as COAs, is a wise practice.

The manufacturing process for 4-Hydroxyphenylboronic Acid involves multi-step synthesis, often starting from readily available precursors. The ability of a supplier to consistently produce this intermediate at scale, with reliable quality, is a testament to their manufacturing expertise and supply chain management. For industrial buyers, partnering with a chemical manufacturer that can provide bulk quantities, flexible packaging options (like 25kg drums), and dependable delivery is key to operational continuity.

In essence, chemical intermediates like 4-Hydroxyphenylboronic Acid are foundational to innovation and production across numerous industries. Their reliable sourcing ensures that researchers and manufacturers can continue to develop and produce the advanced materials and life-saving medicines that shape our world.
