Chemical Structure
Description
5-Hydroxy Rosiglitazone Sulfate (CAS 288853-63-4), molecular formula C18H19N3O7S2 and molecular weight 453.49 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 5-Hydroxy Rosiglitazone Sulfate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 453.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 5-Hydroxy Rosiglitazone Sulfate 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.
