Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Exatecan-d5 mesylate (CAS 2819276-88-3), a certified reference material (molecular formula C24H17D5FN3O4CH4O3S, MW 536.59 g/mol) for analytical method development and quality control.
Structurally, Exatecan-d5 mesylate (C24H17D5FN3O4CH4O3S) contains deuterium isotope labeling, a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 16.5, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 536.59 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
