Description

3,5-Difluoro-4'-Propylbihenyl (CAS NO 137528-87-1) is a high-purity biphenyl derivative distinguished by its specific fluorine substitution pattern. This compound is a critical advanced intermediate in the synthesis of complex organic molecules, particularly in the pharmaceutical and liquid crystal industries. It is essential for researchers and manufacturers developing active pharmaceutical ingredients (APIs) and high-performance electronic display materials.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of novel drug candidates, especially those targeting central nervous system (CNS) disorders and other therapeutic areas.
• Liquid Crystal Material: Serves as a core structural unit in the production of fluorine-containing liquid crystals for advanced display technologies (LCDs).
• Organic Synthesis Reagent: Used in cross-coupling reactions (e.g., Suzuki, Stille) to introduce the difluorinated biphenyl moiety into more complex molecular architectures.
• Agrochemical Research: Employed as an intermediate in the development of new generation pesticides and herbicides with enhanced efficacy.
• Material Science: Investigated for use in organic semiconductors and other electronic materials due to its stable biphenyl core and fluorine atoms.
• Chemical Reference Standard: Used for analytical method development, calibration, and quality control in chemical and pharmaceutical laboratories.
