Description

Benzeneacetaldehyde, 4-Fluoro-α-Methyl-, (+)- (9Ci) CAS NO 305820-73-9 is a chiral, fluorinated aromatic aldehyde derivative, serving as a sophisticated and versatile chiral building block in advanced organic synthesis. Its value lies in the precise introduction of both fluorine and a chiral center into molecular scaffolds, enabling the fine-tuning of physicochemical and biological properties. This high-purity intermediate is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries developing novel active ingredients, particularly where stereochemistry and fluorination are critical for efficacy and patent life.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the research and development of fluorinated active pharmaceutical ingredients (APIs), including potential CNS agents, anti-inflammatory drugs, and enzyme inhibitors.
• Agrochemical Synthesis: Used in creating advanced, stereoselective herbicides, fungicides, and pesticides where the fluorine atom enhances bioavailability and environmental stability.
• Liquid Crystal & OLED Materials: Serves as a precursor for fluorinated and chiral components in electronic display materials and organic light-emitting diodes (OLEDs).
• Asymmetric Catalysis Ligand Precursor: Employed in the synthesis of novel chiral ligands and organocatalysts for stereoselective transformations.
• Flavor & Fragrance Chemistry: Acts as a building block for complex, fluorinated aroma chemicals, modifying scent profiles and stability.
• Advanced Material Research: Utilized in academic and industrial R&D for constructing complex fluoroorganic molecules with tailored properties for material science applications.
