Description

4-Bromobutyl Acetate is a versatile brominated ester compound, valued for its role as a key synthetic intermediate in organic chemistry. Its bifunctional nature, featuring both a reactive bromine atom and an ester group, makes it an essential building block for constructing more complex molecular architectures. This product is primarily utilized by research institutions and industrial manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors for applications such as nucleophilic substitution reactions and polymer modification.

Application

• Pharmaceutical Intermediate: Serves as a crucial precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring butyl chain elongation or functionalization.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators where the bromobutyl moiety is incorporated into the final molecule.
• Polymer & Material Science: Acts as a monomer or cross-linking agent in the development of specialty polymers, coatings, and resins.
• Organic Synthesis Building Block: Employed in nucleophilic substitution (SN2) reactions to introduce the 4-bromobutyl group into target molecules, facilitating carbon chain extension.
• Liquid Crystal & Electronic Chemical Production: Utilized in the manufacturing of intermediates for liquid crystal displays (LCDs) and other electronic materials.
• Flavor & Fragrance Industry: Functions as an intermediate for synthesizing specific ester-based aroma compounds.

Quality Control

Our 4-Bromobutyl Acetate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopic methods (IR, NMR), to ensure high purity and consistency. A Certificate of Analysis (COA) detailing specific results for identity, assay, and impurity profiles is provided with every shipment to guarantee it meets your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids, bases, and oxidizing agents. Recommended storage temperature is between 2°C and 25°C. Keep container tightly sealed when not in use to prevent moisture absorption and volatilization.
