Description

3-Furancarbonyl Chloride, 5-Bromo- (9Ci) is a halogenated furan derivative that serves as a versatile and reactive chemical building block. Its value lies in its bifunctional nature, combining a reactive acid chloride group with a bromine substituent on the furan ring, enabling sequential and site-specific modifications. This compound is primarily needed by researchers and manufacturers in the pharmaceutical and agrochemical industries for the synthesis of novel active ingredients and complex organic intermediates. Its structure makes it particularly useful for constructing heterocyclic frameworks and introducing the furan moiety into target molecules.

Application

• Pharmaceutical Intermediate: A key synthon for the development of novel drug candidates, particularly in medicinal chemistry programs targeting heterocyclic active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the research and production of advanced pesticides, herbicides, and fungicides where the furan ring contributes to biological activity.
• Material Science Research: Employed as a monomer or precursor for synthesizing specialized polymers, ligands, and organic electronic materials.
• Chemical Biology & Proteomics: Acts as a reactive handle for bioconjugation and the synthesis of molecular probes and activity-based protein profiling reagents.
• Organic Synthesis Building Block: Facilitates Friedel-Crafts acylation, amide coupling, and other nucleophilic substitution reactions to create complex molecular architectures.
• Dye & Pigment Intermediate: Used in the synthesis of specialized heterocyclic dyes and colorants.

Quality Control

Our 3-Furancarbonyl Chloride, 5-Bromo- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements of research and process development. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from strong bases, oxidizing agents, and sources of ignition.
