Description

Ethyl 3-Bromobutyrate is a versatile brominated ester building block, essential for introducing the 3-bromobutyryl moiety into complex molecular frameworks. Its primary value lies in its reactivity as an alkylating agent and as a precursor for further functionalization via nucleophilic substitution or elimination reactions. This compound is particularly valuable for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries, where it is used to synthesize active ingredients and advanced intermediates.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring a brominated carbon chain for further cyclization or coupling reactions.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators that incorporate halogenated butyrate structures.
• Organic Synthesis Reagent: Serves as a versatile alkylating agent in nucleophilic substitution reactions and as a precursor for generating Michael acceptors or other unsaturated compounds.
• Flavor & Fragrance Industry: Intermediate for the synthesis of certain esters and lactones that contribute to complex flavor and aroma profiles.
• Polymer Chemistry: Can be used as a monomer or cross-linking agent in the preparation of specialty polymers and resins.
• Chemical Research: A valuable reagent in academic and industrial R&D for method development and exploring new synthetic pathways.

Quality Control

Our Ethyl 3-Bromobutyrate is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for synthetic applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and concentration changes. Recommended storage temperature is 2-8°C for extended stability.
