For chemical engineers and R&D scientists working with advanced materials, a deep understanding of chemical intermediates like N-Octylmethyldichlorosilane (CAS 14799-93-0) is essential. This organosilicon compound possesses a unique set of chemical properties that dictate its utility and handling in industrial settings. As a key product for manufacturers and suppliers, detailing these properties is vital for customers seeking to buy this chemical.

N-Octylmethyldichlorosilane is characterized by its molecular formula C9H20Cl2Si and its structure, which features a silicon atom bonded to a methyl group, an n-octyl chain, and two chlorine atoms. The presence of these two chlorine atoms makes it a highly reactive dichlorosilane. This reactivity is fundamental to its role as a precursor for synthesizing a wide array of organosilicon polymers and compounds. For example, it readily undergoes hydrolysis in the presence of water, forming silanol groups that can then condense to create siloxane bonds, the backbone of silicone materials.

A critical property for handling and storage is its sensitivity to moisture. Reacting rapidly with water and protic solvents, N-Octylmethyldichlorosilane requires anhydrous conditions to maintain its integrity. This moisture sensitivity is a key consideration for procurement managers and logistics teams. The compound's boiling point of approximately 94 °C at 6 mm Hg and its flash point of 209 °F (or 98 °C as per some sources) are also important safety and operational parameters that suppliers must clearly communicate.

Furthermore, its density of around 0.973 g/mL at 25 °C and a refractive index of n20/D 1.444 are important physical characteristics. These properties, along with its appearance as a clear, colorless liquid, help in quality control and product identification. Reputable manufacturers, especially those in China specializing in organosilicon chemistry, provide detailed specifications for their products, including CAS 14799-93-0.

For companies looking to purchase N-Octylmethyldichlorosilane, understanding these chemical properties is the first step in ensuring successful application. Engaging with a knowledgeable supplier who can offer technical data and guidance on handling is crucial for leveraging the full potential of this versatile chemical intermediate.
