Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 247.09 g/mol gives 2-Bromo-N-(5-methylisoxazol-3-yl)butanamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Bromo-N-(5-methylisoxazol-3-yl)butanamide (CAS 877977-08-7), molecular formula C8H11BrN2O2 and molecular weight 247.09 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, 2-Bromo-N-(5-methylisoxazol-3-yl)butanamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 247.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
