Description
CATO supplies N-(5-Chloro-2-(3-(9-(4-fluorobenzyl)-3-oxa-7,9-diazabicyclo[3.3.1]nonan-7-yl)-3-oxoprop-1-en-1-yl)-4-methoxyphenyl)acetamide (CAS 921208-19-7), a certified reference material (molecular formula C25H27ClFN3O4, MW 487.95 g/mol) for analytical method development and quality control.
N-(5-Chloro-2-(3-(9-(4-fluorobenzyl)-3-oxa-7,9-diazabicyclo[3.3.1]nonan-7-yl)-3-oxoprop-1-en-1-yl)-4-methoxyphenyl)acetamide (C25H27ClFN3O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
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.
