Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 595.65 g/mol gives N-tert-Butyloxycarbonyl Silodosin distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
N-tert-Butyloxycarbonyl Silodosin (CAS 160970-07-0), molecular formula C30H40F3N3O6 and molecular weight 595.65 g/mol, is a CATO reference standard with documented purity and traceability.
N-tert-Butyloxycarbonyl Silodosin (C30H40F3N3O6) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
