The field of organic chemistry is constantly seeking efficient and versatile building blocks to construct complex molecules. 3-Bromoisonicotinic acid, identified by its CAS number 13959-02-9, has emerged as a critical intermediate in the synthesis of a wide array of pyridine derivatives, which are prevalent in pharmaceuticals, agrochemicals, and materials science. Its unique chemical structure offers multiple avenues for functionalization, making it a cornerstone for modern synthetic strategies.

The synthetic utility of 3-Bromoisonicotinic acid lies in its strategically placed bromine atom and carboxylic acid group. The bromine atom at the 3-position is an excellent leaving group for nucleophilic substitution reactions and, more significantly, serves as a reactive site for palladium-catalyzed cross-coupling reactions. These reactions, such as Suzuki-Miyaura coupling with boronic acids or Stille coupling with organostannanes, allow for the facile introduction of carbon-carbon bonds, enabling the synthesis of highly functionalized pyridine systems. For researchers looking to buy 3-Bromoisonicotinic acid, its potential in these advanced reactions is a major draw.

As a dedicated supplier and manufacturer, NINGBO INNO PHARMCHEM CO.,LTD. ensures that 3-Bromoisonicotinic acid is available with the high purity required for these sensitive catalytic processes. The reliability of the product, coupled with competitive price options, makes it an attractive choice for laboratories and production facilities alike. Sourcing from a reputable manufacturer in China provides a stable supply chain, crucial for projects with long-term synthetic goals.

Beyond cross-coupling, the carboxylic acid group of 3-Bromoisonicotinic acid can be readily transformed. Esterification, amidation, or reduction to an alcohol are common modifications that can introduce further diversity into the pyridine scaffold. This dual reactivity means that a single starting material can lead to a multitude of target compounds, underscoring its importance as a key intermediate for creating novel pharmaceutical intermediates and specialty chemicals. The ability to efficiently purchase this compound simplifies complex synthetic planning.

In conclusion, 3-Bromoisonicotinic acid (CAS 13959-02-9) is an indispensable tool for synthetic chemists working with pyridine derivatives. Its versatility in coupling reactions and functional group transformations makes it a high-value intermediate. Prioritizing quality and reliable sourcing from established manufacturers is essential for successful and efficient chemical synthesis.
