Description

5-Bromoisatoic Anhydride is a specialized brominated heterocyclic anhydride used as a key synthetic intermediate in advanced organic chemistry. Its value lies in its reactivity as a building block for constructing complex molecules, particularly in the synthesis of active pharmaceutical ingredients (APIs) and functional dyes. This high-purity compound is essential for research and development laboratories, pharmaceutical manufacturers, and fine chemical producers seeking reliable, high-quality intermediates for their critical processes.

Application

• Pharmaceutical Intermediate: A crucial precursor in the synthesis of various active pharmaceutical ingredients (APIs), particularly those containing anthranilic acid or quinazoline cores.
• Agrochemical Synthesis: Used in the development of advanced herbicides, fungicides, and plant growth regulators that require brominated aromatic structures.
• Dye and Pigment Manufacturing: Serves as a building block for creating brominated anthraquinone and other complex dye molecules with specific colorfastness and light-absorption properties.
• Material Science Research: Employed in the synthesis of organic semiconductors, liquid crystals, and polymers where bromine atoms facilitate further functionalization or influence material properties.
• Academic & Industrial R&D: A valuable reagent for medicinal chemistry programs and process chemistry development for novel heterocyclic compounds.
• Custom Synthesis: Used by contract research and manufacturing organizations (CROs/CMOs) for client-specific molecule construction.

Quality Control

Our 5-Bromoisatoic Anhydride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, to ensure it meets exacting standards for research and industrial use. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming identity, purity, and impurity profiles. We support compliance with global regulatory frameworks, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong bases and strong oxidizing agents.
