In the complex world of chemical procurement, precise identification of substances is critical. The Chemical Abstracts Service (CAS) Registry Number, commonly known as a CAS number, serves as a unique identifier for chemical substances. For professionals in the B2B chemical sector, understanding the significance of CAS numbers is fundamental to accurate sourcing and supply chain management. A prime example is Cloperastine hydrochloride, identified by its CAS number 14984-68-0.

The CAS number is a globally recognized, unique numerical sequence assigned to each chemical compound. It eliminates ambiguity that can arise from different nomenclature systems, synonyms, or brand names. For instance, while Cloperastine hydrochloride might have several chemical names or be referred to by product codes, its CAS number 14984-68-0 remains constant. This universality is invaluable when communicating product requirements to manufacturers and suppliers worldwide.

For buyers, referencing the CAS number in inquiries ensures they are procuring the exact chemical needed. When requesting a quote for Cloperastine hydrochloride, including CAS 14984-68-0 in the query guarantees that suppliers understand the specific compound being sought. This is particularly important for pharmaceutical intermediates, where even minor structural differences can impact efficacy and safety. A manufacturer that readily provides the CAS number along with purity specifications (e.g., 99% MIN assay) demonstrates professionalism and product traceability.

Furthermore, CAS numbers are extensively used in regulatory documentation, safety data sheets (SDS), and technical data sheets (TDS). When you need to buy Cloperastine hydrochloride or any other chemical, using its CAS number in all communications and documentation streamlines the process, reduces errors, and ensures compliance. It is a cornerstone of good procurement practice in the chemical industry, facilitating clear and unambiguous transactions between buyers and suppliers.
