Chemical Structure
Description
Based on its molecular formula C12D28NBr, Tetra-n-propyl-d28-ammonium Bromide contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 294.44 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Tetra-n-propyl-d28-ammonium Bromide (CAS 284474-84-6) is a high-purity analytical reference standard with the molecular formula C12D28NBr and a molecular weight of 294.44 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
