Description

3,4-Dibromo-1,2-Epoxybutane is a versatile brominated epoxide intermediate of significant importance in advanced organic synthesis. Its bifunctional reactivity, combining an epoxide ring with bromine substituents, makes it a valuable building block for creating complex molecular architectures. This compound is primarily sought after by research institutions and industrial manufacturers in the pharmaceutical and agrochemical sectors for the development of active ingredients and specialty polymers.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of novel drug candidates and active pharmaceutical ingredients (APIs), particularly those requiring bromine-containing motifs.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and other crop protection agents where the epoxide and bromine functionalities introduce specific biological activity.
• Polymer & Resin Modification: Serves as a cross-linking agent or reactive diluent in epoxy resin systems, enhancing flame retardancy and thermal properties.
• Chemical Research & Development: A valuable reagent in organic chemistry labs for constructing heterocyclic compounds and other complex organic molecules.
• Specialty Chemical Manufacturing: Intermediate for producing surfactants, dyes, and other performance chemicals requiring specific bromo-epoxide chemistry.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
