In the world of chemical procurement, especially within the pharmaceutical sector, precise identification of compounds is paramount. The Chemical Abstracts Service (CAS) Registry Number is the industry standard for this purpose. This article explains the significance of CAS numbers and their role in sourcing vital pharmaceutical intermediates such as 4-Amino-5-chloro-2-methoxy-N-(3-methoxy-4-piperidinyl)benzamide hydrochloride (CAS 221180-26-3).
A CAS Registry Number is a unique numerical identifier assigned to a specific chemical substance. Unlike chemical names, which can vary or have multiple synonyms, a CAS number is unambiguous. For example, knowing the CAS number 221180-26-3 instantly identifies the compound as 4-Amino-5-chloro-2-methoxy-N-(3-methoxy-4-piperidinyl)benzamide hydrochloride. This precision is critical when purchasing chemicals, as it eliminates confusion and ensures that you are acquiring the exact material needed for your application. In pharmaceutical synthesis, where purity and specific structures are vital, using the correct CAS number is essential for ordering the right intermediates, such as those required for Cisapride production (CAS 81098-60-4).
When sourcing pharmaceutical intermediates, cross-referencing the chemical name with its CAS number is a standard best practice. This verification step helps confirm the identity and quality of the product. Reputable suppliers, including manufacturers in China, will always provide the CAS number along with other specifications like purity (e.g., ≥98%) and physical properties (e.g., white solid with a melting point of 276-278 °C dec.). This information ensures transparency and builds trust between the buyer and the supplier.
Understanding CAS numbers also facilitates easier database searches and literature reviews. Whether you are a researcher looking to buy a specific compound for R&D or a procurement manager ensuring supply chain integrity, the CAS number is your most reliable tool. It allows for efficient comparison of offerings from different manufacturers and confirmation that the product meets the required standards for your synthesis process.
For anyone looking to purchase 4-Amino-5-chloro-2-methoxy-N-(3-methoxy-4-piperidinyl)benzamide hydrochloride or any other chemical intermediate, always ensure the CAS number is clearly stated and verified. This simple yet powerful identifier is key to ensuring you buy the correct, high-quality materials needed for successful pharmaceutical development and manufacturing.
