Description

(Dichlorophenyl)Trichlorosilane is a highly reactive organosilicon compound that serves as a critical building block in advanced material synthesis. Its value lies in its ability to introduce functional silane groups onto aromatic systems, enabling precise surface modification and polymer cross-linking. This chemical is essential for manufacturers in the electronics, specialty polymer, and advanced coating industries seeking to enhance material properties like adhesion, hydrophobicity, and thermal stability.

Application

• Surface Treatment Agent: A key precursor for creating hydrophobic and oleophobic coatings on glass, metals, and ceramics.
• Polymer Modification: Used as a cross-linking agent or functional monomer in the synthesis of high-performance silicones and hybrid organic-inorganic polymers.
• Adhesion Promoter: Improves the bonding between organic polymers and inorganic substrates in composite materials and sealants.
• Semiconductor Manufacturing: Employed in the chemical vapor deposition (CVD) process to create thin films and dielectric layers on silicon wafers.
• Intermediate for Silane Coupling Agents: A fundamental starting material for synthesizing more complex bifunctional silanes used in rubber, plastics, and fiberglass reinforcement.
• Pharmaceutical & Agrochemistry Intermediates: Serves as a versatile synthon for introducing the dichlorophenyl moiety into more complex molecules.

Quality Control

Our (Dichlorophenyl)Trichlorosilane is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including gas chromatography (GC) and NMR spectroscopy, to verify identity and assay. Certificates of Analysis (COA) detailing purity and impurity profiles are available upon request to support your quality assurance protocols.

Storage

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