Chemical Structure
Description
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.
CATO supplies N-{[(1S,5S)-8-Oxo-1,5,6,8-tetrahydro-2H-1,5-methano-pyrido[1,2-a][1,5]diazocin-3(4H)-yl]carbonyl}-D-leucine (CAS 1453860-57-5), a certified reference material (molecular formula C18H25N3O4, MW 347.41 g/mol) for analytical method development and quality control.
N-{[(1S,5S)-8-Oxo-1,5,6,8-tetrahydro-2H-1,5-methano-pyrido[1,2-a][1,5]diazocin-3(4H)-yl]carbonyl}-D-leucine (C18H25N3O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
