Chemical Structure
Description
As a certified reference material (CRM), 3-(4-Nitrophenyl)-5,6-dihydroimidazo[2,1-b]thiazole 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.
CATO supplies 3-(4-Nitrophenyl)-5,6-dihydroimidazo[2,1-b]thiazole (CAS 40229-93-4), a certified reference material (molecular formula C11H9N3O2S, MW 247.27 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 3-(4-Nitrophenyl)-5,6-dihydroimidazo[2,1-b]thiazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 247.27 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.
