Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-(Azetidin-3-yl)-1-methyl-1H-1,2,3,4-tetrazole hydrochloride (CAS 1638771-13-7) is a high-purity analytical reference standard with the molecular formula C5H9N5HCl and a molecular weight of 175.62 g/mol.
The molecular framework of 5-(Azetidin-3-yl)-1-methyl-1H-1,2,3,4-tetrazole hydrochloride (C5H9N5HCl) is characterized by a nitrile group, 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.
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.
