Description

Bis(Chloromethyl)Benzene is a versatile aromatic organic compound featuring two reactive chloromethyl groups. This bifunctional structure makes it a valuable chemical intermediate for the synthesis of more complex molecules in advanced manufacturing. It is primarily sought after by the pharmaceutical, agrochemical, and specialty polymer industries for applications requiring the introduction of a benzyl or xylylene moiety. The compound is commercially available under CAS No. 28347-13-9.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for drugs containing benzylamine or xylylene linkers.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and other crop protection agents where its aromatic core provides structural stability.
• Polymer & Resin Production: Serves as a cross-linking agent or monomer in the manufacture of specialty polymers, epoxy resins, and ion-exchange resins.
• Organic Synthesis Reagent: Employed in research and development for introducing chloromethyl or subsequent functional groups into target molecules.
• Dye & Pigment Manufacturing: Acts as a precursor in the synthesis of certain complex dyes and organic pigments.
• Ligand & Chelating Agent Preparation: Useful for creating complexing agents and ligands used in catalysis and metal ion sequestration.

Quality Control

Our Bis(Chloromethyl)Benzene is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay and impurity profile determination by chromatographic methods, to ensure it meets the high standards required for industrial and research applications. A Certificate of Analysis (COA) detailing purity, identity, and specific test results is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture.
