In the precise world of chemical sourcing, particularly for specialized compounds like pharmaceutical intermediates, accurate identification is paramount. The Chemical Abstracts Service (CAS) Registry Number, commonly known as a CAS number, serves as the universal identifier for chemical substances. For procurement managers, R&D scientists, and product formulators, understanding the significance of CAS numbers, such as CAS 25602-68-0 for Nortropinone Hydrochloride, is fundamental to ensuring correct purchasing decisions and avoiding costly errors.
What is a CAS Number?
A CAS number is a unique numerical identifier assigned to every chemical substance described in the open scientific literature. It consists of three parts separated by hyphens, with the last digit acting as a check digit. For example, the CAS number for Nortropinone Hydrochloride is 25602-68-0.
Why are CAS Numbers Crucial in Chemical Procurement?
The primary function of a CAS number is to eliminate ambiguity. Many chemical compounds can have multiple names, synonyms, or trade names, leading to potential confusion. A CAS number, however, refers to a single, specific substance, regardless of its nomenclature. When you need to purchase Nortropinone Hydrochloride, specifying its CAS number (25602-68-0) ensures that suppliers understand exactly which compound you require, irrespective of any regional or proprietary naming conventions.
Benefits of Using CAS Numbers for Sourcing:
Sourcing Nortropinone Hydrochloride Using its CAS Number
When initiating a search for Nortropinone Hydrochloride, using CAS 25602-68-0 in your queries will yield more accurate results. This allows you to quickly identify potential manufacturers and suppliers who offer this specific intermediate. For instance, you can search for 'Nortropinone Hydrochloride CAS 25602-68-0 manufacturer' or 'buy CAS 25602-68-0 price.' This precise approach is vital for obtaining accurate quotes and ensuring you receive a product that meets your exact specifications, like the 97% minimum purity often required for pharmaceutical applications.
In essence, the CAS number is an indispensable tool in the chemical procurement toolkit. By consistently using CAS numbers in your searches and inquiries, you empower yourself to source chemicals with confidence, accuracy, and efficiency.
