Description

Benzoyl Chloride, 2,3,6-Trimethyl- (7Ci,9Ci) CAS NO 54200-87-2 is a specialized aromatic acid chloride derivative, serving as a critical building block in advanced organic synthesis. Its value lies in its high reactivity as an acylating agent, enabling the efficient introduction of the 2,3,6-trimethylbenzoyl moiety into target molecules. This compound is essential for R&D chemists and production teams in the pharmaceutical, agrochemical, and specialty chemical industries who require precise and reliable intermediates for developing active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel active pharmaceutical ingredients (APIs), particularly for compounds requiring a sterically hindered benzoyl group.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators where the trimethyl-substituted ring enhances biological activity and stability.
• Polymer Chemistry: Acts as a monomer or modifying agent in the production of specialty polymers, including polyesters and polyamides, to impart specific thermal or mechanical properties.
• Dye and Pigment Manufacturing: Employed in the synthesis of complex organic dyes and pigments, where it contributes to color fastness and molecular structure.
• Organic Synthesis Reagent: A versatile acylating agent in laboratory and industrial-scale reactions for amide and ester formation under controlled conditions.
• Liquid Crystal & OLED Materials: Serves as a synthetic intermediate for advanced electronic materials requiring specific aromatic architectures.

Quality Control

Our Benzoyl Chloride, 2,3,6-Trimethyl- is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and NMR/IR for structural confirmation, to ensure it meets exacting specifications for sensitive synthetic applications. Certificates of Analysis (COA) documenting all critical parameters are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature and reactivity as a strong acid/organic solvent, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain purity. Keep away from moisture, heat, and incompatible materials such as bases, alcohols, and oxidizing agents.
