Chemical Structure
Description
Methyl 2-({4-[(1E)-{[(4-fluorophenyl)methoxy]imino}methyl]-1-methyl-3-phenyl-1H-pyrazol-5-yl}sulfanyl)benzoate (CAS 321998-49-6) is a high-purity analytical reference standard with the molecular formula C26H22FN3O3S and a molecular weight of 475.53 g/mol.
The molecular framework of Methyl 2-({4-[(1E)-{[(4-fluorophenyl)methoxy]imino}methyl]-1-methyl-3-phenyl-1H-pyrazol-5-yl}sulfanyl)benzoate (C26H22FN3O3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
