In the intricate world of chemistry, precise identification of substances is critical for research, safety, and commerce. The Chemical Abstracts Service (CAS) Registry Number is the universal language for this identification, providing a unique numerical identifier for every chemical substance described in the scientific literature. For professionals working with specialized compounds like 2-(Methyldiphenylsilyl)ethanol, understanding the significance of its CAS number, 40438-48-0, is fundamental to accurate sourcing and communication.

A CAS number is more than just a string of digits; it's a gateway to comprehensive information about a chemical. For 2-(Methyldiphenylsilyl)ethanol (CAS 40438-48-0), this number unlocks access to its chemical structure, physical properties, safety data, known applications, and potential suppliers. R&D scientists and product formulators rely heavily on CAS numbers to ensure they are referencing and procuring the correct material for their experiments and production processes.

When procurement managers search for a specific compound, using the CAS number is often the most efficient and reliable method. It eliminates ambiguity that can arise from varying chemical names or synonyms. For instance, searching for '2-(Methyldiphenylsilyl)ethanol' is important, but specifying 'CAS 40438-48-0' guarantees that suppliers understand precisely which compound is being requested, including its exact isomer or grade if applicable. This precision is especially crucial for specialized organosilicon monomers where subtle structural differences can lead to significant variations in reactivity and application performance.

Furthermore, the CAS number plays a vital role in regulatory compliance and safety information dissemination. Accessing safety data sheets (SDS) or technical specifications through a CAS number ensures that users are aware of the potential hazards and necessary precautions associated with handling the chemical. This is an integral part of responsible chemical management, particularly when dealing with new or less common compounds.

In essence, the CAS number 40438-48-0 acts as a critical identifier for 2-(Methyldiphenylsilyl)ethanol, facilitating clear communication, ensuring accuracy in procurement, and underpinning safety protocols. For anyone involved in the chemical industry, familiarizing oneself with the importance and usage of CAS numbers is a cornerstone of professional practice.
