Description

3,5-Dibromocinnamic Acid is a halogenated cinnamic acid derivative that serves as a versatile and high-value synthetic intermediate in advanced organic chemistry. Its core value proposition lies in its dual bromine substituents, which provide reactive handles for further functionalization, enabling the synthesis of complex molecules. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and material science industries, particularly for developing novel active ingredients and functional polymers.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, especially in medicinal chemistry programs targeting inflammation and metabolic disorders.
• Agrochemical Synthesis: Used in the research and development of new herbicides and fungicides, leveraging its halogenated structure for bioactivity.
• Liquid Crystal & OLED Material Precursor: Serves as a starting material for synthesizing brominated aromatic compounds used in electronic displays and organic light-emitting diodes.
• Polymer Modification: Acts as a monomer or cross-linking agent to introduce bromine functionality into polymers, enhancing flame retardancy or other physical properties.
• Chemical Research & Development: A valuable reagent in academic and industrial R&D for Suzuki-Miyaura and other palladium-catalyzed cross-coupling reactions.
• Fine Chemical Production: Intermediate in the multi-step synthesis of complex fragrances, dyes, and other specialty chemicals.

Quality Control

Our 3,5-Dibromocinnamic Acid is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) with detailed batch-specific results are provided to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 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.
