Description

Benzoyl Chloride, 2,5-Dimethyl- (6Ci,7Ci,8Ci,9Ci) CAS NO 22328-43-4 is a specialized aromatic acid chloride derivative, serving as a critical acylating agent and versatile synthetic intermediate in advanced organic synthesis. Its value lies in the introduction of the 2,5-dimethylbenzoyl moiety, enabling the creation of complex molecules with tailored properties for high-performance applications. This compound is essential for research chemists and industrial manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors who require precise and reliable building blocks for their development pipelines.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing active pharmaceutical ingredients (APIs), particularly those requiring substituted benzoyl groups.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and pesticides where the dimethyl-substituted ring enhances biological activity and stability.
• Dye and Pigment Manufacturing: Acts as an intermediate in creating specialized azo dyes and organic pigments, contributing to color fastness and specific hue properties.
• Polymer Chemistry: Employed as a monomer or modifying agent in the synthesis of specialty polymers, including polyamides and polyesters, to alter thermal and mechanical characteristics.
• Organic Synthesis Reagent: A valuable reagent for Friedel-Crafts acylation and nucleophilic acyl substitution reactions in research and fine chemical production.
• Liquid Crystal and OLED Material Precursor: Used in the synthesis of advanced organic electronic materials due to its ability to form rigid, planar structures.

Quality Control

Our Benzoyl Chloride, 2,5-Dimethyl- is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chromatography (HPLC/GC) and spectroscopic methods, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

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