Description

5-(1,1,1,3,3,3-Hexafluoro-2-Hydroxypropan-2-Yl)-4,5-Dihydroisoxazole-3-Carboxylic Acid CAS NO 444342-51-2 is a high-value, fluorinated isoxazoline carboxylic acid derivative. This compound serves as a critical advanced intermediate in the synthesis of complex molecules, prized for its ability to introduce both a reactive isoxazoline ring and a hexafluoro-tert-butanol moiety. It is primarily sought after by pharmaceutical R&D and agrochemical research teams for developing novel active ingredients.

Application

• Pharmaceutical Intermediate: A key building block for synthesizing novel drug candidates, particularly in medicinal chemistry programs targeting CNS disorders and inflammation.
• Agrochemical Synthesis: Used in the research and development of next-generation herbicides and insecticides, leveraging the stability and bioactivity of the fluorinated isoxazoline core.
• Material Science Research: Employed in the creation of specialty polymers and coatings where the introduction of fluorine atoms can enhance chemical resistance and surface properties.
• Ligand and Catalyst Development: Acts as a precursor for chiral ligands or organocatalysts used in asymmetric synthesis.
• Chemical Biology Probes: Useful for labeling or modifying biomolecules in proteomics and diagnostic assay development due to its reactive carboxylic acid group.
