Description

Benzeneethanol, 4-Fluoro-β-Methyl-, (Betas)- (9Ci) is a specialized fluorinated aromatic alcohol building block of significant interest in advanced organic synthesis. This compound matters for its role as a key chiral intermediate in the development of active pharmaceutical ingredients (APIs) and other high-value fine chemicals. Pharmaceutical R&D laboratories and fine chemical manufacturers need this material to construct complex molecular architectures where the specific stereochemistry and fluorine substitution are critical for biological activity and metabolic stability.

Application

• Pharmaceutical Intermediate: A crucial chiral building block for the synthesis of novel drug candidates, particularly in central nervous system (CNS) and cardiovascular therapeutic areas.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides and herbicides, where the fluorine atom enhances bioactivity and environmental persistence.
• Liquid Crystal & OLED Materials: Serves as a precursor in the development of fluorinated components for electronic display technologies and organic light-emitting diodes.
• Asymmetric Catalysis Research: Employed as a substrate or ligand precursor in the development of new chiral catalysts and methodologies.
• Flavor & Fragrance Chemistry: Potential use in the synthesis of complex, fluorinated aromatic compounds for specialty fragrance applications.
• Polymer Modification: Acts as a monomer or functionalization agent for creating specialty polymers with unique surface properties.

Quality Control

Every batch of Benzeneethanol, 4-Fluoro-β-Methyl-, (Betas)- (9Ci) is produced and tested under a strict quality management system. We ensure compliance with relevant industry standards for chiral intermediates, with a focus on enantiomeric excess (ee) and chemical purity. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing specifications for identity, purity, chiral purity, and impurity profiles.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
