Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 538.04 g/mol gives Silodosin-d6 DiHCl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Silodosin-d6 DiHCl (CAS 1261392-62-4), molecular formula C25H26D6F3N3O4HCl and molecular weight 538.04 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Silodosin-d6 DiHCl (C25H26D6F3N3O4HCl) is characterized by deuterium isotope labeling, a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), Silodosin-d6 DiHCl meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
