Chemical Structure
Description
CATO supplies (S)-Subasumstat (CAS 1858282-76-4), a certified reference material (molecular formula C25H28ClN5O5S2, MW 578.10 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, (S)-Subasumstat is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 578.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), (S)-Subasumstat 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.
