In the vast and complex world of chemistry, precise identification of substances is paramount. Every chemical compound, from the simplest molecule to the most complex pharmaceutical, needs a unique identifier to ensure clear communication, accurate record-keeping, and safe handling. This is where CAS Registry Numbers, or CAS numbers, come into play. For a compound like 2-Hydroxy-5-Picoline, its CAS number, 1003-68-5, serves as its unmistakable fingerprint in the global chemical landscape.

The Chemical Abstracts Service (CAS), a division of the American Chemical Society, assigns these unique numerical identifiers to every chemical substance described in the scientific literature. A CAS number consists of three parts, separated by hyphens, such as the 1003-68-5 for 2-Hydroxy-5-Picoline. This systematic approach ensures that regardless of how many different names a compound might have – including synonyms, trade names, or systematic IUPAC names – its CAS number remains constant and unambiguous.

For professionals in industries like pharmaceuticals, manufacturing, and research, understanding and utilizing CAS numbers is fundamental. When sourcing materials, such as 2-Hydroxy-5-Picoline, specifying the CAS number 1003-68-5 leaves no room for error. It ensures that the correct chemical is ordered, avoiding costly mistakes or potential safety hazards. Suppliers like NINGBO INNO PHARMCHEM CO.,LTD. prominently feature CAS numbers in their product listings, such as for 2-Hydroxy-5-Picoline, to facilitate accurate procurement.

The reliability of CAS numbers is crucial for global trade and regulatory compliance. They are recognized internationally, allowing for seamless transactions and the exchange of chemical information across borders. When a chemical synthesis requires a specific intermediate, searching by its CAS number is often the most efficient and reliable method. The ease with which one can buy 2-Hydroxy-5-Picoline by referencing its CAS number highlights the system's effectiveness.

Furthermore, CAS numbers are linked to a wealth of information about a substance, including its chemical properties, safety data sheets (MSDS), and relevant scientific literature. Accessing this information is critical for safe handling, storage, and application. For instance, the chemical properties of 2-Hydroxy-5-Picoline, such as its appearance as a white to yellow powder and its purity greater than 99%, are cataloged and readily available through its CAS number.

In conclusion, CAS Registry Numbers are indispensable tools in the chemical industry. They provide a universal language for identifying chemical substances, ensuring accuracy in research, manufacturing, and trade. The CAS number 1003-68-5 for 2-Hydroxy-5-Picoline is more than just a sequence of digits; it is a gateway to essential information and a guarantee of chemical identity, underpinning the reliability and safety of chemical processes worldwide.
