Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 675.68 g/mol gives Silodosin Glucuronide-D4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Silodosin Glucuronide-D4 (CAS 2851016-14-1), molecular formula C31H36D4F3N3O10 and molecular weight 675.68 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Silodosin Glucuronide-D4 (C31H36D4F3N3O10) contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 675.68 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
