Description

Ethyl 4,6-Dichloro-3-Formyl-1H-Indole-2-Carboxylate is a high-purity, multi-functional indole derivative that serves as a critical advanced intermediate in modern synthetic chemistry. Its unique molecular structure, featuring reactive formyl and ester groups on a halogenated indole scaffold, makes it an indispensable building block for constructing complex heterocyclic systems. This compound is primarily sought after by research institutions and pharmaceutical manufacturers engaged in the development of novel active pharmaceutical ingredients (APIs) and agrochemicals.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of complex indole-based drug candidates, particularly for oncology and central nervous system (CNS) therapeutic areas.
• Agrochemical Research: Used in the development of new-generation herbicides, fungicides, and plant growth regulators that require halogenated heterocyclic cores.
• Material Science: Serves as a monomer or functionalizing agent for creating specialized polymers and organic electronic materials with unique optoelectronic properties.
• Chemical Synthesis: An essential building block for synthesizing more complex indole alkaloids and other fused heterocyclic compounds in academic and industrial R&D.
• Dye & Pigment Industry: Utilized in the production of high-performance, light-fast organic dyes and pigments due to its stable, functionalized indole structure.

Quality Control

Our Ethyl 4,6-Dichloro-3-Formyl-1H-Indole-2-Carboxylate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is subjected to rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory documentation 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). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which may affect product stability and performance. Keep away from incompatible materials.
