Chemical Structure
Description
Structurally, 4-{[(9R)-9-Hydroxy-2-azatricyclo[9.4.0.0³,⁸]pentadeca-1(11),3,5,7,12,14-hexaene-2-carbonyl]amino}butanoic acid (C19H20N2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 340.37 g/mol, it falls into the moderately-high-molecular-weight range. 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).
CATO supplies 4-{[(9R)-9-Hydroxy-2-azatricyclo[9.4.0.0³,⁸]pentadeca-1(11),3,5,7,12,14-hexaene-2-carbonyl]amino}butanoic acid (CAS 1523541-97-0), a certified reference material (molecular formula C19H20N2O4, MW 340.37 g/mol) for analytical method development and quality control.
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.
