In the global chemical industry, accurate identification and unambiguous communication are paramount. The Chemical Abstracts Service (CAS) Registry Number, commonly known as a CAS number, serves as a unique identifier for chemical substances. Each CAS number consists of three parts separated by hyphens, typically in the format XX-XX-X or a variation thereof. This standardized system ensures that chemists, researchers, and regulatory bodies worldwide can precisely identify chemical compounds, regardless of variations in nomenclature or naming conventions. Understanding the significance of CAS numbers is fundamental when engaging in chemical procurement.

For instance, when a company like NINGBO INNO PHARMCHEM CO.,LTD. offers a product such as 2-[4-(9,9-diphenyl-9H-fluoren-2-yl)phenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane, its CAS number, 1813574-72-9, provides an essential reference point. This allows buyers to confirm they are acquiring the exact chemical substance required for their specific applications, whether it's for organic synthesis, the development of OLED materials, or as a pharmaceutical intermediate. The CAS number eliminates ambiguity and ensures that the correct material is ordered, preventing costly errors and delays.

The role of CAS numbers extends beyond simple identification; they are crucial for regulatory compliance, safety data sheets (SDS), and inventory management. When purchasing chemicals, verifying the CAS number listed by the supplier is a critical step. It assures the buyer of the product's authenticity and helps in navigating complex regulatory landscapes. NINGBO INNO PHARMCHEM CO.,LTD., as a reputable supplier, prominently features CAS numbers for its extensive range of chemical products, underscoring their commitment to clarity and accuracy in the chemical supply chain.

Furthermore, CAS numbers are instrumental in research literature and databases, allowing for efficient retrieval of information related to a specific compound, including its properties, synthesis methods, and applications. When searching for organic synthesis building blocks or specific intermediates, using the CAS number is often the most direct and reliable method. Therefore, familiarizing oneself with the CAS number of desired compounds, such as 2-[4-(9,9-diphenyl-9H-fluoren-2-yl)phenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane, is a fundamental aspect of informed chemical procurement and successful research endeavors.
