In the precise and highly regulated world of chemical procurement, especially within the pharmaceutical sector, the Chemical Abstracts Service (CAS) Registry Number is an indispensable identifier. Each unique chemical substance is assigned a CAS number, a globally recognized standard that ensures absolute clarity and avoids ambiguity. For professionals seeking specific compounds, such as those vital for drug synthesis, understanding and correctly referencing CAS numbers is critical. This article delves into the importance of CAS numbers, focusing on a key pharmaceutical intermediate: Carbamic acid, N-[5-[(4-methylphenyl)sulfonyl]-5H-pyrrolo[2,3-b]pyrazin-2-yl]-, ethyl ester, identified by CAS 1869118-24-0.

Carbamic acid, N-[5-[(4-methylphenyl)sulfonyl]-5H-pyrrolo[2,3-b]pyrazin-2-yl]-, ethyl ester (CAS 1869118-24-0) is a complex organic molecule with a specific structure and properties that make it invaluable as an intermediate, particularly in the synthesis of pharmaceuticals like Upadacitinib. For purchasing managers and R&D scientists, accurately specifying 'CAS 1869118-24-0' when requesting quotes or placing orders is the first step in ensuring they receive the correct material. Sourcing from reputable manufacturers and suppliers, such as NINGBO INNO PHARMCHEM CO.,LTD., who clearly list CAS numbers with their product specifications, provides confidence in product identity and quality.

The role of a chemical supplier extends beyond merely providing a product. It involves guaranteeing that the product matches the specified CAS number and associated purity requirements (e.g., ≥99.0% for this particular intermediate). Companies like NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer based in China, pride themselves on meticulous cataloging and quality assurance, making the procurement process smoother and more reliable. When you are ready to buy this intermediate for your research or production, always verify the CAS number to ensure you are purchasing from a trusted source.

The chemical industry, particularly the pharmaceutical sector, relies on absolute precision. Misidentification of a chemical intermediate can lead to costly errors, project delays, and compromised product safety. Therefore, paying close attention to CAS numbers, molecular formulas (C16H16N4O4S), and physical descriptions (white powder) is not just good practice; it's essential for operational success. We encourage all professionals seeking high-quality chemical intermediates to utilize CAS numbers as a primary point of reference.
