Description

4-Bromocinnamic Acid is a versatile brominated aromatic compound that serves as a key synthetic intermediate in advanced organic chemistry. Its value lies in the reactive bromine atom and the cinnamic acid backbone, which allow for selective functionalization and incorporation into more complex molecular architectures. This product is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and material science industries, where it is used to develop active ingredients and novel functional materials.

Application

• Pharmaceutical Intermediate: A crucial building block in the synthesis of potential drug candidates, particularly those targeting inflammation and central nervous system disorders.
• Agrochemical Synthesis: Used in the research and development of novel herbicides and plant growth regulators.
• Liquid Crystal & OLED Material Precursor: Serves as a starting material for synthesizing brominated aromatic cores used in electronic display technologies.
• Polymer Modification: Incorporated as a monomer or cross-linking agent to introduce bromine functionality into polymers for flame retardancy or specific reactivity.
• Organic Synthesis & Catalysis Research: Employed in Heck coupling, Suzuki-Miyaura cross-coupling, and other palladium-catalyzed reactions to form carbon-carbon bonds.
• Chemical Reference Standard: Used for analytical method development, calibration, and quality control in laboratory settings.

Quality Control

Our 4-Bromocinnamic Acid is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment, guaranteeing traceability and consistent quality.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, the container should be amber-colored or stored in a dark place.
