2-(Cyclopentylthio)-1-(4-fluorophenyl)-5-(4-methoxyphenyl)-1H-imidazole CAS 1206991-52-7 chemical structure

Description

The occurrence of 2-(Cyclopentylthio)-1-(4-fluorophenyl)-5-(4-methoxyphenyl)-1H-imidazole is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(Cyclopentylthio)-1-(4-fluorophenyl)-5-(4-methoxyphenyl)-1H-imidazole (CAS 1206991-52-7), molecular formula C21H21FN2OS and molecular weight 368.47 g/mol, is a CATO reference standard with documented purity and traceability.

2-(Cyclopentylthio)-1-(4-fluorophenyl)-5-(4-methoxyphenyl)-1H-imidazole (C21H21FN2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), 2-(Cyclopentylthio)-1-(4-fluorophenyl)-5-(4-methoxyphenyl)-1H-imidazole 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.
