Description

4-Isobutylbenzoyl Chloride is a versatile and reactive organic intermediate belonging to the class of benzoyl chlorides. Its primary value lies in its role as a key acylating agent for introducing the 4-isobutylbenzoyl moiety into target molecules, enabling the synthesis of more complex chemical architectures. This compound is essential for research and development chemists and process engineers in the pharmaceutical, agrochemical, and specialty chemical industries, where it is used to create active ingredients and advanced materials.

Application

• Pharmaceutical Intermediate: Critical building block for the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs) and other active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators that require the isobutylbenzene structure.
• Polymer Chemistry: Serves as a monomer or modifying agent in the creation of specialty polymers and liquid crystal materials.
• Organic Synthesis & Research: A fundamental reagent for Friedel-Crafts acylation and other reactions to form ketones, amides, and esters in academic and industrial R&D.
• Dye and Pigment Manufacturing: Acts as an intermediate in the synthesis of complex organic dyes and colorants.
• Flavor and Fragrance Industry: Used in the controlled synthesis of specific aromatic compounds.

Quality Control

Our 4-Isobutylbenzoyl Chloride is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided and available upon request, supporting compliance in cGMP and ISO 9001 environments.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. This material is hygroscopic (moisture-sensitive) and reacts violently with water, strong bases, and alcohols. Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation from moisture.
