Description

Thieno[2,3-C]Pyridine-7-Carboxylic Acid (9Ci) is a high-purity heterocyclic carboxylic acid building block of significant interest in advanced organic synthesis. This compound serves as a critical intermediate for the development of novel pharmacologically active molecules and functional materials. It is primarily sought after by research and development teams in the pharmaceutical, agrochemical, and specialty chemical industries for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: A key synthon for the research and development of new active pharmaceutical ingredients (APIs), particularly in medicinal chemistry programs targeting kinase inhibitors and other heterocyclic-based therapeutics.
• Agrochemical Research: Used in the synthesis of novel herbicides, fungicides, and insecticides, leveraging its unique fused-ring structure for bioactivity.
• Material Science Precursor: Serves as a building block for organic electronic materials, such as organic semiconductors and light-emitting diodes (OLEDs), due to its conjugated π-system.
• Chemical Biology Probe Development: Employed in the design and synthesis of molecular probes and labeled compounds for biochemical and diagnostic research.
• Custom Synthesis & Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for the production of bespoke compounds and small-scale commercial batches.
