Description

(2-Mercaptoethyl)Trimethylsilane is a versatile organosilicon compound featuring a reactive thiol (mercapto) group. This dual functionality makes it a valuable intermediate for introducing silicon-containing moieties and enabling thiol-based coupling reactions in advanced material synthesis. It is primarily sought by R&D and production teams in the pharmaceutical, agrochemical, and specialty polymer industries for applications ranging from surface modification to the synthesis of functionalized silanes and controlled release systems.

Application

• Silane Coupling Agent: Used to modify surfaces of inorganic materials like glass, silica, and metals to improve adhesion with organic polymers.
• Pharmaceutical Intermediate: Serves as a key building block in synthesizing active pharmaceutical ingredients (APIs) and prodrugs with targeted release profiles.
• Polymer Modification: Acts as a chain transfer agent or cross-linking agent in the production of specialty silicones, rubbers, and adhesives.
• Agrochemical Synthesis: Employed in the manufacture of silicon-containing pesticides and herbicides to enhance efficacy and stability.
• Surface Functionalization: Used to create self-assembled monolayers (SAMs) on gold and other surfaces for sensor and microelectronic applications.
• Hydrophobic Coating Precursor: A component in formulations for water-repellent and corrosion-resistant coatings.

Quality Control

Our (2-Mercaptoethyl)Trimethylsilane is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets precise customer specifications. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at room temperature (15-25°C). Due to its highly volatile and light-sensitive nature, containers should be kept tightly sealed and away from heat, sparks, and open flame. Keep under an inert atmosphere such as nitrogen for long-term storage to prevent oxidation.
