What is NCATS ribociclib and what does “C23H30N8O” mean?
“C23H30N8O” is the molecular formula for ribociclib, meaning the compound contains 23 carbons (C), 30 hydrogens (H), 8 nitrogens (N), and 1 oxygen (O). This formula matches ribociclib’s known chemical composition.
NCATS typically refers to resources from the U.S. National Center for Advancing Translational Sciences, which often provide chemical/compound records (for example, through public databases) that list identifiers and molecular properties such as molecular formula.
Does ribociclib have the same molecular formula across salts or forms?
Yes. Ribociclib itself has the molecular formula C23H30N8O. If you see the formula vary in a listing, it usually means you are looking at a salt or a different chemical form (for instance, different counterions in a salt form) rather than the free base.
What is ribociclib used for?
Ribociclib is a cyclin-dependent kinase (CDK) 4/6 inhibitor used in oncology, commonly in hormone receptor-positive, HER2-negative advanced or metastatic breast cancer in combination with endocrine therapy. (The exact indication depends on country/regulatory label.)
Where can I verify the exact NCATS entry details?
