Description

4-Bromo-2-Ethylaniline is a halogenated aniline derivative that serves as a versatile and critical building block in advanced organic synthesis. Its molecular structure, featuring both bromine and an ethyl group on the aromatic ring, makes it a valuable intermediate for constructing complex molecules with tailored properties. This compound is primarily sought after by research institutions and manufacturers in the pharmaceutical and agrochemical sectors for the development of active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a halogenated aniline core structure.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and insecticides, where the bromine atom facilitates further functionalization.
• Dye and Pigment Manufacturing: Serves as a starting material for azo dyes and other complex colorants, contributing to chromophore development.
• Liquid Crystal and OLED Materials: Employed in the research and development of electronic display materials due to its aromatic and halogen-substituted properties.
• Polymer Modification: Acts as a monomer or additive to introduce aromatic amines into polymer chains, altering material characteristics.
• Chemical Research & Development: A valuable reagent for academic and industrial R&D in organic chemistry, medicinal chemistry, and material science.

Quality Control

Our 4-Bromo-2-Ethylaniline is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee compliance with your research or production specifications.

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 nature of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from heat, sparks, and open flames.
