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.
1073608-19-1 5-(4-Chloro-butyl)-1-cyclohexyl-1H-tetrazole-d11 5-(4-Chlorobutyl)-1-cyclohexyltetrazole-d11 (CAS 1073608-19-1) is a high-purity analytical reference standard with the molecular formula C11H8D11ClN4 and a molecular weight of 253.82 g/mol.
Owing to deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 1073608-19-1 5-(4-Chloro-butyl)-1-cyclohexyl-1H-tetrazole-d11 5-(4-Chlorobutyl)-1-cyclohexyltetrazole-d11 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 253.82 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
