Description

(4-Bromomethylphenyl)Acetic Acid Ethyl Ester is a versatile brominated aromatic ester that serves as a key synthetic intermediate in advanced organic chemistry. Its value lies in the reactive bromomethyl group, which facilitates efficient alkylation and further functionalization, enabling the construction of complex molecular architectures. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries developing active ingredients and novel materials.

Application

• Pharmaceutical Intermediate: A crucial building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds targeting central nervous system and inflammatory diseases.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators, where the aromatic core provides structural stability.
• Liquid Crystal & OLED Material Precursor: Serves as a starting material for synthesizing specialized aromatic compounds used in electronic displays and organic light-emitting diodes.
• Polymer Modification Agent: Employed to introduce functional aromatic groups into polymer chains, enhancing material properties like thermal stability and refractive index.
• Cross-coupling Reaction Substrate: The bromine atom makes it an excellent substrate for palladium-catalyzed reactions like Suzuki, Heck, and Sonogashira couplings for carbon-carbon bond formation.
• Chemical Research & Development: A valuable reagent in academic and industrial R&D labs for exploring new synthetic pathways and creating novel chemical entities.

Quality Control

Our (4-Bromomethylphenyl)Acetic Acid Ethyl Ester is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, GC, NMR, and FTIR, to ensure identity, purity, and consistency. We provide full traceability and detailed Certificates of Analysis (COA) with every shipment, confirming compliance with customer specifications and industry best practices.

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 heat, sparks, and open flame.
