4,5-Bis(4-methoxyphenyl)-1h-imidazole-2-thiol CAS 39908-69-5

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.

4,5-Bis(4-methoxyphenyl)-1h-imidazole-2-thiol (CAS 39908-69-5), molecular formula C17H16N2O2S and molecular weight 312.39 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C17H16N2O2S, 4,5-Bis(4-methoxyphenyl)-1h-imidazole-2-thiol contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 312.39 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
