Description

2-Thiophenecarboxylicacid,3-Mercapto-(9Ci) is a specialized heterocyclic building block containing both carboxylic acid and thiol functional groups on a thiophene scaffold. This unique bifunctional structure makes it a valuable intermediate for synthesizing complex molecules in advanced research and development. It is particularly relevant for chemists and manufacturers in the pharmaceutical and agrochemical sectors seeking to develop novel active compounds.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly in areas requiring thiophene-based heterocycles.
• Agrochemical Synthesis: Used in the research and development of new pesticides and herbicides, leveraging its reactive sites for structural diversification.
• Material Science Research: Serves as a precursor for functionalized polymers or organic electronic materials due to the conjugated thiophene system.
• Ligand and Catalyst Development: The thiol and carboxylic acid groups allow for chelation and coordination to metal centers, useful in catalysis.
• Chemical Biology Probes: Employed in the design of probes and linkers for studying biological systems, where the thiol group enables conjugation.

Quality Control

Our 2-Thiophenecarboxylicacid,3-Mercapto-(9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) with detailed specifications are available upon request to support your quality assurance processes.

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 sensitivity to oxidation, it is recommended to handle and store the material under an inert atmosphere such as nitrogen or argon for long-term stability.
