In the realm of chemical manufacturing and material science, understanding the core properties and applications of key intermediates is paramount for any B2B procurement manager or R&D scientist. One such critical compound is Trimethylsilanol, identified by its CAS number 1066-40-6. This organosilicon compound plays a pivotal role in the creation of a wide array of silicone-based materials that are indispensable across numerous industries.

What is Trimethylsilanol?

Trimethylsilanol, also known by its IUPAC name hydroxy(trimethyl)silane, is a volatile, colorless liquid. Its molecular formula is C3H10OSi, with a molecular weight of approximately 90.20 g/mol. The presence of the Si-OH (silanol) group is what gives this molecule its significant chemical reactivity and utility as an intermediate. It is a weak acid, comparable in acidity to orthosilicic acid, which dictates its behavior in various chemical reactions.

Key Chemical and Physical Properties

For procurement professionals and formulators, a deep understanding of a chemical's properties is vital. Trimethylsilanol exhibits a boiling point around 99°C and a melting point of approximately 9.5°C. Its density is about 0.8139. Crucially, it is soluble in water, with a solubility of 1.00 mg/ml, and also exhibits solubility in common organic solvents like chloroform. Its flammability is noted, with a flash point of 1°C, underscoring the need for appropriate handling and storage. When considering where to buy Trimethylsilanol, examining the purity levels offered by a potential manufacturer in China is essential for ensuring your downstream processes are not impacted by impurities.

The Indispensable Role in Silicone Production

Trimethylsilanol's primary value lies in its function as a crucial intermediate in the synthesis of various silicone products. It serves as a building block for silicone oils, silicone rubbers, and silicone resins. The Si-OH group can react to form Si-O-Si linkages, which are the backbone of polysiloxane chains. This makes it an essential component for companies manufacturing silicone-based sealants, coatings, adhesives, and elastomers. If you are looking for a reliable supplier of Trimethylsilanol for these extensive applications, focusing on consistent quality and supply is key.

Diverse Applications Beyond Silicone Synthesis

Beyond its foundational role in silicone polymer production, Trimethylsilanol offers other valuable applications. It can be used to create hydrophobic coats on silicate surfaces, enhancing water repellency and durability in various materials. Furthermore, research indicates that Trimethylsilanol exhibits antimicrobial properties, opening up potential uses in applications requiring enhanced hygiene and resistance to microbial growth. These specialized uses highlight the versatility of this organosilicon compound, making it attractive for companies seeking to innovate in material science and product development.

Sourcing Trimethylsilanol: A Procurement Perspective

For businesses looking to procure Trimethylsilanol, identifying a trustworthy manufacturer and supplier is critical. Factors such as product purity (often specified as ≥97.5% or ≥95%), packaging options, and regulatory compliance are paramount. When comparing Trimethylsilanol price points, it's important to balance cost with the assurance of quality and a stable supply chain. Many B2B buyers look for suppliers who can provide technical support and customized specifications to meet specific R&D or manufacturing requirements.
