In the intricate world of chemistry, precise identification of substances is paramount. This is where Chemical Abstracts Service (CAS) Registry Numbers come into play. Each CAS number is a unique, alphanumeric identifier assigned to a specific chemical substance, ensuring that scientists, researchers, and industries worldwide can refer to compounds with absolute clarity, regardless of their common names or proprietary labels.

Take, for instance, D-Threo-Methylphenidate Hydrochloride. Its CAS number, 19262-68-1, is its definitive passport in the chemical universe. This number is not arbitrary; it signifies a unique chemical entity, and its consistent use across various databases, safety data sheets (SDS), and research papers eliminates ambiguity. When a D-Threo-Methylphenidate Hydrochloride manufacturer lists this CAS number, it immediately communicates the exact substance being offered.

The importance of CAS numbers is particularly evident when discussing chemical intermediates. Whether you are looking to buy D-Threo-Methylphenidate Hydrochloride for pharmaceutical synthesis or as a key component in fine chemical manufacturing, referencing its CAS number ensures that you are obtaining the precise compound required. This avoids costly errors and ensures the integrity of your processes.

For any chemical, from bulk industrial compounds to specialized intermediates like D-Threo-Methylphenidate Hydrochloride, the CAS number is the universal language. It guarantees that you are dealing with a specific molecule with defined properties, such as a 99% minimum assay and a molecular formula of C14H20ClNO2. Understanding and utilizing CAS numbers is a fundamental practice for anyone involved in chemical research, procurement, or production.
