In the vast and intricate world of chemistry, precise identification of substances is paramount. This is where CAS numbers, or Chemical Abstracts Service Registry Numbers, play a critical role. Each unique chemical substance is assigned a distinct CAS number, serving as a universal identifier. For the widely used compound, Melatonin, its CAS number is 73-31-4. NINGBO INNO PHARMCHEM CO.,LTD. understands the significance of this identifier and ensures its high quality melatonin powder is accurately cataloged.
A CAS number is a unique numerical sequence, typically consisting of three parts separated by hyphens, which identifies a specific chemical substance without relying on its name or structural formula alone. For example, Melatonin Powder is consistently identified by CAS 73-31-4, irrespective of regional nomenclature or trade names. This standardization is vital for researchers, manufacturers, and regulatory bodies globally. It eliminates ambiguity and ensures that everyone is referring to the same chemical entity.
NINGBO INNO PHARMCHEM CO.,LTD. supplies high quality melatonin powder, and correctly referencing its CAS 73-31-4 is fundamental to their operations and client interactions. Whether a client is looking to buy melatonin powder for pharmaceutical applications, dietary supplements, or research, the CAS number serves as a clear and unambiguous point of reference. This is particularly important when sourcing pharmaceutical grade melatonin, where absolute certainty in the identity of the compound is non-negotiable.
The consistency provided by CAS numbers streamlines processes across the chemical industry. It simplifies inventory management, enhances safety protocols by clearly identifying hazardous substances, and facilitates regulatory compliance. For companies like NINGBO INNO PHARMCHEM CO.,LTD., who are involved in the wholesale melatonin supply, the CAS number is an integral part of their product information, ensuring that clients receive precisely what they order.
Furthermore, the presence of CAS 73-31-4 on product documentation, such as Certificates of Analysis or Safety Data Sheets for melatonin powder, signifies a commitment to transparency and accuracy. It allows customers to cross-reference information and verify the identity of the chemical substance independently. This attention to detail is a hallmark of reputable suppliers in the chemical sector.
In conclusion, CAS numbers are indispensable tools for chemical identification. For Melatonin Powder (CAS 73-31-4), this unique identifier ensures clarity and accuracy in a global marketplace. NINGBO INNO PHARMCHEM CO.,LTD.'s dedication to providing high quality melatonin powder, coupled with their adherence to precise chemical identification through CAS numbers, underscores their commitment to serving the pharmaceutical and health industries effectively and reliably.
