Chemical Structure
Description
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.
CATO supplies 8-Methoxypyrene-1,3,6-trisulfonate (trisodium) (CAS 82962-86-5), a certified reference material (molecular formula C17H9Na3O10S3, MW 538.41 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, 8-Methoxypyrene-1,3,6-trisulfonate (trisodium) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 538.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 8-Methoxypyrene-1,3,6-trisulfonate (trisodium) 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.
