Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 412.32 g/mol gives Oxitropium bromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Oxitropium bromide (CAS 30286-75-0), molecular formula C19H26NO4Br and molecular weight 412.32 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C19H26NO4Br, Oxitropium bromide contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 412.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
