CATO supplies (2s)-2-amino-3-hydroxy-n-[2-methoxy-5-[(1z)-2-(3,4,5-trimethoxyphenyl)ethenyl]phenyl]propanamide (S,Z)-2-Amino-3-hydroxy-N-(2-methoxy-5-(3,4,5-trimethoxystyryl)phenyl)propanamide 181816-48-8 ave-8062 ombrabulin ombrabulin(ave-8062) propanamide,2-amino-3-hydroxy-n-[2-methoxy-5-[(1z)-2-(3,4,5-trimethoxyphenyl)ethenyl]phenyl]-,(2s)- (CAS 181816-48-8), a certified reference material (molecular formula C21H26N2O6, MW 402.44 g/mol) for analytical method development and quality control.
The molecular framework of (2s)-2-amino-3-hydroxy-n-[2-methoxy-5-[(1z)-2-(3,4,5-trimethoxyphenyl)ethenyl]phenyl]propanamide (S,Z)-2-Amino-3-hydroxy-N-(2-methoxy-5-(3,4,5-trimethoxystyryl)phenyl)propanamide 181816-48-8 ave-8062 ombrabulin ombrabulin(ave-8062) propanamide,2-amino-3-hydroxy-n-[2-methoxy-5-[(1z)-2-(3,4,5-trimethoxyphenyl)ethenyl]phenyl]-,(2s)- (C21H26N2O6) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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).
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.
