Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Butyl 6-bromo-4-morpholinoquinoline-2-carboxylate (CAS 887589-60-8), a certified reference material (molecular formula C18H21BrN2O3, MW 393.27 g/mol) for analytical method development and quality control.
The molecular framework of Butyl 6-bromo-4-morpholinoquinoline-2-carboxylate (C18H21BrN2O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
