In the complex landscape of pharmaceutical manufacturing, the role of intermediates cannot be overstated. These chemical compounds serve as the foundational building blocks for Active Pharmaceutical Ingredients (APIs), directly influencing the quality, efficacy, and cost-effectiveness of the final drug product. At NINGBO INNO PHARMCHEM CO., LTD., we understand the critical nature of these components and are dedicated to providing high-quality pharmaceutical intermediates.

One such vital intermediate is 2-Chloro-8-cyclopentyl-5-Methylpyrido[2,3-d]pyrimidin-7(8H)-one, identified by CAS number 1013916-37-4. This compound plays a pivotal role in the synthesis of Palbociclib. Palbociclib is a groundbreaking medication used to treat certain types of advanced or metastatic breast cancer, specifically hormone receptor (HR)-positive, HER2-negative cases. The effectiveness of Palbociclib hinges on the precise synthesis and purity of its constituent intermediates, making 2-Chloro-8-cyclopentyl-5-Methylpyrido[2,3-d]pyrimidin-7(8H)-one an indispensable element in its production chain.

The synthesis of Palbociclib involves a multi-step process, and the reliable supply of high-purity intermediates like the one in question is paramount. Pharmaceutical companies rely on specialized suppliers who can guarantee consistency and quality, often requiring GMP certification. NINGBO INNO PHARMCHEM CO., LTD. is committed to meeting these stringent demands, ensuring that our products contribute to the success of our clients' drug development and manufacturing efforts. Our expertise in organic synthesis allows us to produce intermediates like 2-Chloro-8-cyclopentyl-5-Methylpyrido[2,3-d]pyrimidin-7(8H)-one with the required specifications.

Understanding the chemical properties and application of CAS 1013916-37-4 is crucial for researchers and manufacturers. This compound, often appearing as a yellow powder, has a molecular formula of C13H14ClN3O. Its purity level is critical, with industry standards often requiring levels of 98% or higher. Beyond its role as a direct intermediate, it is also recognized as a Palbociclib impurity, making it important for quality control and analytical testing to ensure the absence of such impurities in the final API. This dual role underscores its significance in the entire lifecycle of Palbociclib production.
