1-(4-Fluorophenyl)-1H-tetrazole-5-thiol (CAS 1544-79-2) is a high-purity analytical reference standard with the molecular formula C7H5FN4S and a molecular weight of 196.20 g/mol.
The molecular framework of 1-(4-Fluorophenyl)-1H-tetrazole-5-thiol (C7H5FN4S) is characterized by a nitrile group, sulfur-containing functionality, fluorine substitution, an aromatic ring system. 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.
