Description

Benzoyl Chloride, 5-Chloro-2-Hydroxy- is a versatile and reactive chlorinated aromatic compound that serves as a key synthetic intermediate. Its value lies in its bifunctional nature, combining a reactive acid chloride group with a phenolic hydroxyl group, enabling its use in the construction of more complex molecules. This product is essential for research chemists and manufacturers in the pharmaceutical and agrochemical industries seeking to develop new active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: A crucial building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a chlorinated phenolic backbone.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and pesticides, where its chlorinated aromatic structure contributes to biological activity.
• Dye and Pigment Manufacturing: Acts as an intermediate for creating chlorinated azo dyes and other complex colorants.
• Polymer Chemistry: Employed as a monomer or modifying agent for specialty polymers, such as polyesters and polycarbonates, to introduce specific functional groups.
• Organic Synthesis Reagent: Utilized in academic and industrial R&D for Friedel-Crafts acylation reactions and the preparation of esters and amides.
• UV Stabilizer Production: Serves as a precursor in the manufacture of light-absorbing compounds used as stabilizers in plastics and coatings.

Quality Control

Our Benzoyl Chloride, 5-Chloro-2-Hydroxy- is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including chromatography (HPLC/GC) and spectroscopic methods, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available upon request, supporting compliance in regulated applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and strong acid/organic solvent nature, the container must be kept tightly sealed to exclude moisture and stored separately from bases and oxidizing agents.
