For R&D scientists and product formulators, a deep understanding of a chemical compound's properties is fundamental to its successful application. Dimethyloctadecyl[3-(trimethoxysilyl)propyl]ammonium chloride, identified by CAS number 27668-52-6, is a specialty chemical with a complex yet highly useful structure. Its unique combination of functionalities makes it a valuable ingredient in various advanced formulations.

At its core, this compound is a silane derivative featuring a quaternary ammonium cation. The chemical name itself highlights its key components: an octadecyl group (a long, 18-carbon saturated alkyl chain), two methyl groups, a propyl linker, and the trimethoxysilyl group. The trimethoxysilyl moiety (-Si(OCH3)3) is the reactive silane part, capable of undergoing hydrolysis and condensation reactions. This allows it to form strong bonds with inorganic substrates or create cross-linked siloxane networks. The quaternary ammonium head, with its positive charge and long alkyl chain, imparts surfactant properties, conditioning effects, and potentially antimicrobial activity. The overall molecular formula is C26H58ClNO3Si, with a molecular weight of approximately 496.28 g/mol. Typically, it appears as a clear liquid.

As a dedicated manufacturer and supplier, we ensure that the Dimethyloctadecyl[3-(trimethoxysilyl)propyl]ammonium chloride we provide meets high standards for purity and performance. The specific details of its properties, such as assay (often around 60% or higher in solution) and water content, are critical for formulators to consider. The hydrolytic sensitivity of the trimethoxysilyl groups means storage conditions are important; it should be kept in tightly sealed containers, away from moisture and high temperatures.
