Description

3,5-Bis(Acetyloxy)Benzoyl Chloride is a high-purity, reactive organic intermediate featuring both benzoyl chloride and acetyl-protected phenolic functionalities. This compound matters for its role as a versatile building block in the synthesis of complex molecules, enabling the introduction of the 3,5-dihydroxybenzoyl moiety under controlled conditions. It is primarily needed by research and development chemists and process engineers in the pharmaceutical, agrochemical, and advanced materials industries for creating active ingredients and specialty polymers.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring a protected dihydroxybenzene core.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators where its reactive acid chloride group facilitates amide and ester bond formation.
• Polymer Chemistry: Serves as a monomer or cross-linking agent in the production of specialty polyesters, polyamides, and high-performance engineering plastics.
• Liquid Crystal & OLED Materials: A precursor in the synthesis of complex organic molecules used in electronic displays and optoelectronic devices.
• Dye & Pigment Manufacturing: Intermediate for creating advanced colorants and photostable dyes.
• Academic & Contract Research: A valuable reagent for methodological development and exploratory synthesis in organic chemistry laboratories.

Quality Control

Every batch of 3,5-Bis(Acetyloxy)Benzoyl Chloride is manufactured and tested under a strict quality management system. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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, bases, and oxidizing agents.
