Description
CATO supplies N'-(4,6-dimethyl-3-(1H-pyrrol-1-yl)thieno[2,3-b]pyridine-2-carbonyl)benzenesulfonohydrazide (CAS 478029-14-0), a certified reference material (molecular formula C20H18N4O3S2, MW 426.51 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, N'-(4,6-dimethyl-3-(1H-pyrrol-1-yl)thieno[2,3-b]pyridine-2-carbonyl)benzenesulfonohydrazide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 426.51 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), N'-(4,6-dimethyl-3-(1H-pyrrol-1-yl)thieno[2,3-b]pyridine-2-carbonyl)benzenesulfonohydrazide 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.
