CATO supplies 2-(3-(2-(4-Butoxyphenyl)-6-oxothiazolo[3,2-b][1,2,4]triazol-5(6H)-ylidene)-2-oxoindolin-1-yl)acetic acid (CAS 606963-57-9), a certified reference material (molecular formula C24H20N4O5S, MW 476.50 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, 2-(3-(2-(4-Butoxyphenyl)-6-oxothiazolo[3,2-b][1,2,4]triazol-5(6H)-ylidene)-2-oxoindolin-1-yl)acetic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 476.50 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).
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), 2-(3-(2-(4-Butoxyphenyl)-6-oxothiazolo[3,2-b][1,2,4]triazol-5(6H)-ylidene)-2-oxoindolin-1-yl)acetic acid 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.
