Description

2-Thiophenecarbonylchloride,5-Ethoxy-(9Ci) is a specialized organosulfur building block featuring a reactive acid chloride group and an ethoxy substituent on the thiophene ring. This compound is valued for its role as a key synthetic intermediate in the development of complex molecules, particularly in pharmaceutical and agrochemical research. It is primarily sought by R&D chemists and process development scientists in the fine chemical, pharmaceutical, and advanced material sectors for constructing novel heterocyclic compounds and functional materials.

Application

• Pharmaceutical Intermediate: A crucial building block for the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders and anti-infective agents.
• Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, and insecticides that incorporate the thiophene moiety for enhanced biological activity.
• Material Science Research: Serves as a monomer or precursor for the development of conductive polymers, organic semiconductors, and non-linear optical (NLO) materials.
• Ligand and Catalyst Development: Employed in the creation of specialized ligands for transition metal catalysis and organocatalysts used in asymmetric synthesis.
• Chemical Biology Probes: Utilized to synthesize molecular probes and tags for studying biological processes and protein interactions.

Quality Control

Our 2-Thiophenecarbonylchloride,5-Ethoxy-(9Ci) is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and GC-MS, to ensure high purity and consistent performance for research and development applications. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming identity, purity, and impurity profiles.

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 degradation. Keep away from strong acids and incompatible materials.
