(E)-{[6-(4-bromophenyl)imidazo[2,1-b][1,3]thiazol-5-yl]methylidene}[(2-chloro-6-fluorophenyl)methoxy]amine CAS 691883-98-4

Description

(E)-{[6-(4-bromophenyl)imidazo[2,1-b][1,3]thiazol-5-yl]methylidene}[(2-chloro-6-fluorophenyl)methoxy]amine (CAS 691883-98-4) is a high-purity analytical reference standard with the molecular formula C19H12BrClFN3OS and a molecular weight of 464.74 g/mol.

The molecular framework of (E)-{[6-(4-bromophenyl)imidazo[2,1-b][1,3]thiazol-5-yl]methylidene}[(2-chloro-6-fluorophenyl)methoxy]amine (C19H12BrClFN3OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

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.
