Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-(tert-Butyl)-3-((1-(4-fluorophenyl)-1H-tetrazol-5-yl)methyl)urea (CAS 897623-91-5) is a high-purity analytical reference standard with the molecular formula C13H17FN6O and a molecular weight of 292.31 g/mol.
Structurally, 1-(tert-Butyl)-3-((1-(4-fluorophenyl)-1H-tetrazol-5-yl)methyl)urea (C13H17FN6O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 292.31 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
