Chemical Structure
Description
6-Bromo-2-oxo-N-(2-(piperidin-1-yl)ethyl)-2H-chromene-3-carboxamide (CAS 81309-18-4) is a high-purity analytical reference standard with the molecular formula C17H19BrN2O3 and a molecular weight of 379.25 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, 6-Bromo-2-oxo-N-(2-(piperidin-1-yl)ethyl)-2H-chromene-3-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 379.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 6-Bromo-2-oxo-N-(2-(piperidin-1-yl)ethyl)-2H-chromene-3-carboxamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
