Chemical Structure
Description
9α-Bromo Flunisolide (CAS CATO-C4X-16483) is a high-purity analytical reference standard with the molecular formula C24H30BrFO6 and a molecular weight of 513.39 g/mol.
Based on its molecular formula C24H30BrFO6, 9α-Bromo Flunisolide contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 513.39 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
