Chemical Structure
Description
(R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(2,4,5-trimethoxyphenyl)propanoic acid (C27H27NO7) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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).
(R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(2,4,5-trimethoxyphenyl)propanoic acid (CAS 1260605-07-9), molecular formula C27H27NO7 and molecular weight 477.51 g/mol, is a CATO reference standard with documented purity and traceability.
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.
