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 2-(2-Ethoxybenzylidene)benzo[4,5]imidazo[2,1-b]thiazol-3(2H)-one (CAS 30065-04-4), a certified reference material (molecular formula C18H14N2O2S, MW 322.38 g/mol) for analytical method development and quality control.
The molecular framework of 2-(2-Ethoxybenzylidene)benzo[4,5]imidazo[2,1-b]thiazol-3(2H)-one (C18H14N2O2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 2-(2-Ethoxybenzylidene)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.
