As a certified reference material (CRM), (E)-4-(6-(4-fluorophenyl)imidazo[2,1-b]thiazol-5-yl)but-3-en-2-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.
(E)-4-(6-(4-fluorophenyl)imidazo[2,1-b]thiazol-5-yl)but-3-en-2-one (CAS 691869-99-5), molecular formula C15H11FN2OS and molecular weight 286.32 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (E)-4-(6-(4-fluorophenyl)imidazo[2,1-b]thiazol-5-yl)but-3-en-2-one (C15H11FN2OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
