Understanding the foundational chemistry of key industrial compounds is crucial for innovation and process optimization. Trimethylsilanol, identified by CAS 1066-40-6, is a prime example of such a compound, serving as a critical intermediate in the fine chemical sector. NINGBO INNO PHARMCHEM CO.,LTD. sheds light on the synthesis and intrinsic properties that make Trimethylsilanol indispensable.

The primary method for synthesizing Trimethylsilanol involves the hydrolysis of trimethylchlorosilane (TMCS). This reaction, typically carried out under controlled conditions, results in the formation of the Si-OH bond characteristic of silanols. The process yields a colorless, clear liquid with a relatively low boiling point, making it amenable to various downstream processing techniques. The molecular formula, C3H10OSi, and molecular weight of approximately 90.2 g/mol, define its fundamental chemical identity.

Key physical properties of Trimethylsilanol include its liquid state at room temperature, with a melting point of -4.5°C and a boiling point of around 90°C. Its density is approximately 0.8139 g/cm³, and it possesses a refractive index of 1.3889. The compound is soluble in water to a limited extent (1.00 mg/ml) and also exhibits solubility in various organic solvents. Its hydrolytic sensitivity is noted as low under neutral conditions, contributing to its stability in certain formulations.

The reactivity of the Si-OH group in Trimethylsilanol is central to its utility. It can undergo reactions to form Si-H bonds, and it serves as a crucial intermediate in the preparation of organosilicon alcoholates and a wide spectrum of polysiloxanes. This makes it a foundational chemical for the production of silicone oils, silicone rubbers, and silicone resins, materials that are ubiquitous in modern technology and industry. For manufacturers sourcing essential organosilicon intermediates, the consistent quality and detailed chemical properties of Trimethylsilanol are paramount.
