Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
Capivasertib Impurity 32 (CAS CATO-C4X-331232) is a certified pharmaceutical impurity reference standard with the molecular formula C21H29N5O5 and a molecular weight of 431.49 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Capivasertib Impurity 32 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 431.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
