Description

3,4-Diamino-5-Bromobenzoic Acid is a high-purity, multifunctional aromatic building block of significant interest in advanced organic synthesis. Its core value lies in the strategic placement of reactive amino and bromo substituents on a benzoic acid scaffold, enabling precise molecular construction. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical sectors, where it serves as a critical precursor for developing novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key synthon for the synthesis of complex heterocyclic compounds, potential drug candidates, and active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, and plant growth regulators.
• Dye and Pigment Manufacturing: Serves as a precursor for specialized azo dyes and high-performance pigments due to its diamine functionality.
• Material Science Research: Employed in the creation of organic semiconductors, metal-organic frameworks (MOFs), and advanced polymers.
• Chemical Biology Probes: Useful for synthesizing labeled compounds and molecular probes for biochemical research and diagnostics.
• Cross-Coupling Reactions: The bromo substituent makes it a valuable substrate for palladium-catalyzed reactions like Suzuki, Heck, and Buchwald-Hartwig aminations.

Quality Control

Our 3,4-Diamino-5-Bromobenzoic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, it is recommended to handle under an inert atmosphere for long-term storage and to minimize exposure to air and moisture.
