Description

13-(Trichlorosilylmethyl)Heptacosane is a specialized organosilicon compound with a long-chain alkyl group terminated by a reactive trichlorosilyl functionality. This unique structure makes it a valuable intermediate for creating hydrophobic and oleophobic surfaces, as well as for modifying polymers and inorganic materials. It is primarily utilized by R&D chemists and material scientists in the advanced materials, specialty coatings, and surface treatment industries.

Application

• Surface Modification Agent: Used to impart water-repellent (hydrophobic) and oil-repellent (oleophobic) properties to glass, metals, and ceramics.
• Coupling Agent: Acts as a molecular bridge to improve adhesion between organic polymers and inorganic fillers or substrates in composite materials.
• Silicone Intermediate: Serves as a key building block in the synthesis of custom polysiloxanes and silicone-based polymers with long alkyl side chains.
• Nanomaterial Functionalization: Employed to coat nanoparticles (e.g., silica, metal oxides) to enhance dispersion in non-polar media and tailor surface properties.
• Lubricant & Release Agent Precursor: Used in the development of high-performance lubricant additives and mold release agents.
• Research & Development: A critical reagent for academic and industrial research exploring novel hybrid organic-inorganic materials.

Quality Control

Every batch of 13-(Trichlorosilylmethyl)Heptacosane is produced and tested under stringent quality management protocols. We ensure consistent purity and performance through advanced analytical techniques including GC, NMR, and FTIR. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee it meets your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Recommended storage temperature is 2-8°C for long-term stability.
