Description

2-Thiophenecarboxylicacid,4-Amino-3-Methoxy-(9Ci) CAS NO 608537-78-6 is a specialized heterocyclic building block featuring both amino and methoxy functional groups on a thiophene carboxylic acid core. This unique molecular architecture makes it a valuable intermediate for the synthesis of complex organic molecules, particularly in advanced research and development. It is primarily sought after by pharmaceutical and agrochemical R&D teams for creating novel active compounds and by fine chemical manufacturers producing high-value specialty chemicals.

Application

• Pharmaceutical Intermediate: A key synthon for the development of novel drug candidates, particularly in therapeutic areas targeting the central nervous system, inflammation, or infectious diseases.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides, herbicides, or fungicides where the thiophene moiety can impart specific biological activity.
• Material Science Research: Serves as a precursor for functionalized polymers, organic semiconductors, or conductive materials due to the electron-rich thiophene ring.
• Ligand and Catalyst Development: The amino and carboxylic acid groups allow for chelation with metals, making it useful for creating novel ligands in catalytic systems.
• Dye and Pigment Intermediate: Employed in the synthesis of specialized dyes and organic pigments where heterocyclic structures are required for color and stability.
• Academic and Industrial R&D: A critical reagent for methodological studies in organic chemistry and for exploring new synthetic pathways in fine chemical production.

Quality Control

Our 2-Thiophenecarboxylicacid,4-Amino-3-Methoxy-(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 applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and batch-to-batch consistency.

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 after opening to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
