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.
2-(Benzylthio)-1-(2,4-dichloro-5-isopropoxyphenyl)-1H-imidazole (CAS 338967-21-8), molecular formula C19H18Cl2N2OS and molecular weight 393.33 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(Benzylthio)-1-(2,4-dichloro-5-isopropoxyphenyl)-1H-imidazole (C19H18Cl2N2OS) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
