Description

Benzoyl Chloride, 3-(2-Methylpropoxy)- (9Ci) is a specialized organic intermediate featuring a benzoyl chloride core functionalized with an isobutoxy side chain. This molecular architecture makes it a valuable building block for synthesizing more complex molecules, particularly in fine chemical and pharmaceutical research. It is primarily sought after by R&D chemists and process development scientists working in advanced organic synthesis. The compound, identified by CAS NO 443290-10-6, is essential for introducing specific functional groups into target structures.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of active pharmaceutical ingredients (APIs) and drug candidates, particularly those requiring benzoyl-protected or functionalized aromatic systems.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and pesticides where its reactive acid chloride group enables the formation of amide or ester linkages.
• Polymer Chemistry: Acts as a monomer or modifying agent in the production of specialty polymers, including polyesters and polyamides, to impart specific chemical resistance or thermal properties.
• Liquid Crystal & OLED Materials: Employed in the synthesis of organic electronic materials and liquid crystal compounds due to its ability to form stable mesogenic cores.
• Dye & Pigment Manufacturing: Functions as an intermediate in creating complex organic dyes and high-performance pigments.
• Cross-Coupling Reactions: Utilized in palladium-catalyzed reactions, such as Suzuki or Heck couplings, as an electrophilic coupling partner.
• Peptide & Protein Research: Can be used for the selective acylation of amino groups in peptide synthesis and bioconjugation strategies.
• Chemical Research & Development: A versatile reagent for academic and industrial R&D exploring new synthetic methodologies and novel compound libraries.

Quality Control

Our Benzoyl Chloride, 3-(2-Methylpropoxy)- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography (HPLC/GC) and spectroscopic methods (NMR, IR), to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment. We adhere to cGMP guidelines where applicable to support our customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Keep away from heat, open flames, and incompatible materials such as strong bases, alcohols, and amines.
