The efficacy of chemical synthesis hinges on a deep understanding of the properties and reactivity of the constituent molecules. 4-Bromophthalic Anhydride (CAS 86-90-8) is a compound whose chemical structure provides a versatile foundation for numerous synthetic pathways. NINGBO INNO PHARMCHEM CO.,LTD. emphasizes the importance of mastering the fundamental chemistry of such intermediates to achieve optimal results.

At its heart, 4-Bromophthalic Anhydride is an organic compound belonging to the class of phthalic anhydrides, further functionalized with a bromine atom. Its chemical formula, C8H3BrO3, reveals a molecular weight of approximately 227.01 g/mol. The presence of the anhydride ring makes it highly reactive towards nucleophiles. This reactivity is key to its widespread use as a synthesis intermediate, particularly in the formation of esters and amides, which are prevalent in pharmaceuticals and polymers.

The bromine atom attached to the aromatic ring opens up additional avenues for chemical modification. It acts as a leaving group in nucleophilic aromatic substitution reactions or can participate in metal-catalyzed cross-coupling reactions, such as Suzuki, Stille, or Sonogashira couplings. These reactions are invaluable for constructing complex carbon frameworks and introducing diverse functional groups into molecules, a process critical for organic synthesis.

For companies seeking to buy 4-Bromophthalic Anhydride online, understanding its reaction profile is crucial. Its typical physical state as a white powder with a moderate melting point (around 107°C) indicates relative stability, but like many anhydrides, it is sensitive to moisture and can hydrolyze to the corresponding phthalic acid. Proper storage in inert conditions is therefore recommended.
