Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Cepharanthine.
CATO supplies Cepharanthine (CAS 481-49-2), a certified reference material (molecular formula C37H38N2O6, MW 606.71 g/mol) for analytical method development and quality control.
Structurally, Cepharanthine (C37H38N2O6) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 20.0, corresponding to approximately 20 ring(s) or double-bond equivalent(s). With a molecular weight of 606.71 g/mol, it falls into the high-molecular-weight range. 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 analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
