Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-((2,5-Dimethyl-1-phenyl-1H-pyrrol-3-yl)methylene)benzo[4,5]imidazo[2,1-b]thiazol-3(2H)-one.
CATO supplies 2-((2,5-Dimethyl-1-phenyl-1H-pyrrol-3-yl)methylene)benzo[4,5]imidazo[2,1-b]thiazol-3(2H)-one (CAS 347323-96-0), a certified reference material (molecular formula C22H17N3OS, MW 371.45 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 2-((2,5-Dimethyl-1-phenyl-1H-pyrrol-3-yl)methylene)benzo[4,5]imidazo[2,1-b]thiazol-3(2H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 371.45 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-((2,5-Dimethyl-1-phenyl-1H-pyrrol-3-yl)methylene)benzo[4,5]imidazo[2,1-b]thiazol-3(2H)-one 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.
