In the relentless fight against cancer, the development of targeted therapies has revolutionized treatment paradigms. Palbociclib, a potent CDK 4/6 inhibitor, stands as a testament to this progress, offering a vital therapeutic option for patients with hormone receptor-positive, HER2-negative advanced or metastatic breast cancer. The efficacy of such advanced pharmaceuticals hinges critically on the quality and availability of their constituent intermediates.

One such crucial intermediate is 2-chloro-8-cyclopentyl-5-methylpyrido[2,3-d]pyrimidin-7(8H)-one, bearing the CAS number 1013916-37-4. This complex organic molecule serves as a foundational building block in the intricate synthesis pathway of Palbociclib. Its precise chemical structure and high purity are paramount to ensuring the final drug product’s safety, efficacy, and stability. Any deviation in quality at this intermediate stage can have significant repercussions on the overall therapeutic outcome.
