Chlorotri-n-Butylsilane, identified by CAS number 995-45-9, is a chemical compound that plays a significant role across several scientific and industrial sectors. Its chemical formula, C12H27ClSi, hints at its organosilicon nature, and its common designation as tributylsilyl chloride underscores its structural features. For professionals in procurement and R&D, understanding its physical and chemical properties, as well as its safe handling requirements, is fundamental to its effective utilization.

The compound is typically described as a colorless liquid. Key physical properties often cited include a boiling point in the range of 250-252 °C (at atmospheric pressure, though specific values may vary with supplier data) and a density around 0.879 g/mL at 25 °C. Its refractive index is noted as approximately 1.446 at 20 °C. A critical characteristic of Chlorotri-n-Butylsilane is its sensitivity to moisture. Upon contact with water or humid air, it readily hydrolyzes, releasing hydrochloric acid and forming silanol derivatives. This reactivity means that the compound must be stored and handled under dry conditions, preferably under an inert atmosphere such as nitrogen, to maintain its integrity and prevent unwanted reactions or degradation.

In terms of safety, Chlorotri-n-Butylsilane is classified as corrosive and can cause severe skin burns and eye damage. It may also cause respiratory irritation. Therefore, appropriate personal protective equipment (PPE), including chemical-resistant gloves, eye protection (safety goggles or face shield), and protective clothing, is mandatory when working with this substance. Adequate ventilation, such as working in a fume hood, is also essential to minimize inhalation exposure to vapors or HCl fumes generated during hydrolysis. Procurement managers should ensure that suppliers provide comprehensive Safety Data Sheets (SDS) detailing all hazards and recommended safety precautions.
