(E)-[(2,6-Dichlorophenyl)methoxy]({6-[(4-methylphenyl)sulfanyl]imidazo[2,1-b][1,3]thiazol-5-yl}methylidene)amine (CAS 339022-99-0), molecular formula C20H15Cl2N3OS2 and molecular weight 448.39 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (E)-[(2,6-Dichlorophenyl)methoxy]({6-[(4-methylphenyl)sulfanyl]imidazo[2,1-b][1,3]thiazol-5-yl}methylidene)amine (C20H15Cl2N3OS2) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
