Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 414.43 g/mol gives Darusentan-[13C,d3] distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Darusentan-[13C,d3] (CAS 1261392-44-2), a certified reference material (molecular formula C21[13C]H19D3N2O6, MW 414.43 g/mol) for analytical method development and quality control.
Structurally, Darusentan-[13C,d3] (C21[13C]H19D3N2O6) contains deuterium isotope labeling, a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.5, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 414.43 g/mol, it falls into the moderately-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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
