Description

4-Bromoindole-3-Carboxaldehyde is a versatile and high-value brominated indole derivative, serving as a critical synthetic intermediate in advanced organic chemistry. Its primary value lies in its dual functional groups—the aldehyde and the bromine substituent—which make it a key building block for constructing complex heterocyclic frameworks. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, particularly for the synthesis of novel drug candidates, bioactive molecules, and specialized fine chemicals.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of potent kinase inhibitors, serotonin receptor modulators, and other biologically active indole-based compounds.
• Agrochemical Research: Used in the development of new herbicides, fungicides, and plant growth regulators that leverage the indole scaffold.
• Material Science: Serves as a monomer or functionalizing agent in the creation of organic semiconductors, conductive polymers, and advanced organic materials.
• Chemical Synthesis: Employed in palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Heck) and as a substrate for constructing complex polycyclic structures via cyclization reactions.
• Bioconjugation & Probe Development: The aldehyde group is useful for creating fluorescent probes, bioconjugates, and molecular tags for diagnostic and research applications.

Quality Control

Our 4-Bromoindole-3-Carboxaldehyde is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC, NMR, and GC-MS, to verify identity and purity while monitoring for key impurities. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider keeping under an inert atmosphere (e.g., nitrogen or argon) to maintain stability and purity.
