Description

2,4-Difluoro-Phenylthioacetic Acid (Ws205036) is a high-purity fluorinated aromatic thioacetic acid derivative, serving as a critical building block in advanced organic synthesis. Its value lies in providing a versatile scaffold for introducing both fluorine atoms and a reactive thioacetic acid moiety into target molecules, enabling precise modulation of chemical and physical properties. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, particularly for developing novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), especially for drugs targeting central nervous system (CNS) disorders, anti-infectives, and oncology.
• Agrochemical Synthesis: Building block for developing new-generation herbicides, fungicides, and pesticides, where the difluorophenyl group enhances bioavailability and metabolic stability.
• Ligand and Catalyst Development: Used in the preparation of specialized ligands for transition metal catalysis and organocatalysts due to the electron-withdrawing fluorine atoms and sulfur functionality.
• Material Science Research: Intermediate for synthesizing monomers or additives aimed at creating polymers with specific optical, electronic, or surface properties.
• Chemical Biology Probes: Serves as a starting material for creating fluorescent tags, affinity labels, or other molecular probes used in biochemical research and diagnostic assays.
