Description

2-(4-Fluorophenyl)-2,6-Dihydro-4H-Thieno[3,4-C]Pyrazol-3-Amine is a high-purity, advanced pharmaceutical intermediate featuring a fused thienopyrazole heterocyclic core with a fluorinated aromatic substituent. This compound is of significant commercial value for its role as a critical building block in the synthesis of novel active pharmaceutical ingredients (APIs), particularly in therapeutic areas requiring targeted molecular scaffolds. Research and development teams in the pharmaceutical, agrochemical, and specialty chemical industries require this precise intermediate to drive innovation in drug discovery and material science programs.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of novel drug candidates, especially those targeting central nervous system (CNS) disorders, oncology, and anti-inflammatory pathways.
• Agrochemical Research: Used in the development of new generation pesticides and herbicides, where the fluorophenyl and thienopyrazole motifs can contribute to biological activity.
• Material Science: Investigated as a monomer or functional component in the creation of advanced organic electronic materials, such as organic semiconductors or light-emitting diodes (OLEDs).
• Chemical Biology Probe: Utilized in academic and industrial research to study enzyme inhibition or protein-ligand interactions due to its specific heterocyclic structure.
• Custom Synthesis & Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for client-specific synthesis projects requiring this specialized heterocycle.

Quality Control

Our 2-(4-Fluorophenyl)-2,6-Dihydro-4H-Thieno[3,4-C]Pyrazol-3-Amine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (NMR, MS), to ensure it meets the high standards required for research and development applications. Certificates of Analysis (COA) with detailed chromatographic data and impurity profiles are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This compound is light-sensitive (store away from light) and may be hygroscopic (moisture-sensitive); therefore, containers should be kept sealed under an inert atmosphere when not in use to prevent degradation and moisture uptake.
