In the complex world of chemical procurement and research, accuracy is key. The Chemical Abstracts Service (CAS) Registry Number is a unique identifier assigned to every chemical substance described in the open scientific literature. For professionals working with specific compounds, like Hexacosanamide, N-[(1S,2S,3R)-1-[(a-D-galactopyranosyloxy)methyl]-2,3-dihydroxyheptadecyl]- (CAS 158021-47-7), understanding and utilizing the CAS number is fundamental to accurate sourcing and application.

The CAS number acts as a universal language for chemicals, eliminating ambiguity that can arise from different nomenclature systems or common names. When a researcher or procurement manager searches to buy a specific chemical, using its CAS number ensures they are identifying the exact substance they need. For Hexacosanamide, the CAS number 158021-47-7 precisely identifies this glycolipid derivative, distinguishing it from other similar compounds and preventing costly errors.

Reliable suppliers and manufacturers, including those in China, invariably list the CAS number prominently in their product descriptions. This allows buyers to quickly verify that they are looking at the correct material. For instance, when seeking Hexacosanamide for diagnostic reagent development, confirming the CAS number is the first step in ensuring the purity and specifications (like the common 98% white powder form) meet the application's demands. This precision is vital for ensuring the efficacy of sensitive assays or the performance of cosmetic formulations.

Furthermore, the CAS number is instrumental in regulatory compliance, safety data sheet (SDS) retrieval, and literature searches. When you purchase chemicals, the associated CAS number on the documentation is critical. It provides an unambiguous link to vital safety and handling information. Therefore, prioritizing suppliers who accurately provide and utilize CAS numbers is a hallmark of a professional and trustworthy chemical sourcing operation, ensuring that your selection of materials, like this specific Hexacosanamide derivative, is always precise and reliable.
