2-[(4-Fluorophenyl)methanesulfonyl]-1-methyl-4,5-bis(2-methylpropyl)-1H-imidazole CAS 866049-05-0

Description

2-[(4-Fluorophenyl)methanesulfonyl]-1-methyl-4,5-bis(2-methylpropyl)-1H-imidazole (CAS 866049-05-0), molecular formula C19H27FN2O2S and molecular weight 366.49 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-[(4-Fluorophenyl)methanesulfonyl]-1-methyl-4,5-bis(2-methylpropyl)-1H-imidazole (C19H27FN2O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 366.49 g/mol, it falls into the moderately-high-molecular-weight range. 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-[(4-Fluorophenyl)methanesulfonyl]-1-methyl-4,5-bis(2-methylpropyl)-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.
