Description

Benzoyl Fluoride, 4-Methoxy- (9Ci) CAS NO 701-53-1 is a specialized fluorinated aromatic building block of significant interest in advanced organic synthesis. This compound matters for its role as a key precursor in the development of pharmaceuticals, agrochemicals, and functional materials, where its unique fluorine and methoxy substituents enable precise molecular modifications. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries seeking to introduce fluorinated motifs into complex molecules.

Application

• Pharmaceutical Intermediate: A critical building block for synthesizing active pharmaceutical ingredients (APIs), particularly those requiring fluorinated aromatic rings for enhanced metabolic stability and bioavailability.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and pesticides, where the fluorine atom can improve biological activity and environmental persistence.
• Liquid Crystal & OLED Material Precursor: Serves as a starting material for creating fluorinated organic compounds used in electronic displays and optoelectronic devices.
• Cross-Coupling Reactions: Functions as an electrophilic coupling partner in palladium-catalyzed reactions (e.g., Suzuki, Stille) for constructing biaryl systems.
• Fluorination Reagent Research: Employed in methodological studies to develop new fluorination techniques and understand reaction mechanisms.
• Polymer Modification: Used to introduce fluorinated benzoyl groups into polymer chains, altering physical properties like solubility, thermal stability, and surface energy.

Quality Control

Our Benzoyl Fluoride, 4-Methoxy- (9Ci) is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity, essential for sensitive synthetic applications. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing purity, identity, and impurity profiles as determined by advanced analytical techniques. Our quality systems are designed to support cGMP and ISO standards for customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area 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 hydrolysis. Keep away from strong acids and incompatible organic solvents.
