Description

1-Bromo-4-Ethylcyclohexane is a versatile halogenated cycloalkane building block of significant interest in advanced organic synthesis. Its value lies in the strategic placement of the bromine and ethyl substituents, which allows for selective functionalization and the construction of complex molecular architectures. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries seeking to develop new active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of novel drug candidates, particularly those requiring functionalized cyclohexane scaffolds.
• Agrochemical Synthesis: Used in the development of advanced pesticides and herbicides, where the bromine atom acts as a reactive handle for further coupling.
• Liquid Crystal & OLED Material Research: Acts as a starting material for creating alkyl-cyclohexyl components used in electronic display technologies.
• Organic Synthesis Building Block: Employed in cross-coupling reactions (e.g., Suzuki, Negishi) and nucleophilic substitutions to introduce the 4-ethylcyclohexyl moiety.
• Flavor & Fragrance Industry: Potential intermediate for the synthesis of musky or woody aroma chemicals based on modified cyclohexane structures.
• Polymer Modification: Can be used to introduce functional groups into polymer chains to alter physical properties like solubility or thermal stability.

Quality Control

Our 1-Bromo-4-Ethylcyclohexane is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including GC, HPLC, and NMR, to ensure identity, purity, and consistency. We provide detailed Certificates of Analysis (COA) with every shipment, confirming compliance with agreed specifications. Our commitment to traceability and reliability supports your R&D and production needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from strong acids and incompatible materials. Recommended storage temperature is 2-8°C for long-term stability, though short-term storage at 15-25°C is acceptable. Keep container tightly sealed when not in use to prevent moisture absorption and volatilization.
