5-(4-Chlorophenyl)-1-(2,4-dichloro-5-methoxyphenyl)-1H-tetrazole (CAS 338961-04-9) is a high-purity analytical reference standard with the molecular formula C14H9Cl3N4O and a molecular weight of 355.61 g/mol.
The molecular framework of 5-(4-Chlorophenyl)-1-(2,4-dichloro-5-methoxyphenyl)-1H-tetrazole (C14H9Cl3N4O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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.
