Description
Compared with other compounds in its class, the molecular weight of 275.25 g/mol gives 5-(4-Fluorophenyl)-1H-imidazol-2-amine hemisulfate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-(4-Fluorophenyl)-1H-imidazol-2-amine hemisulfate (CAS 1177317-21-3), a certified reference material (molecular formula C9H8FN3H2O4S, MW 275.25 g/mol) for analytical method development and quality control.
The molecular framework of 5-(4-Fluorophenyl)-1H-imidazol-2-amine hemisulfate (C9H8FN3H2O4S) is characterized by a nitrogen-containing heterocyclic scaffold, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
