Chemical Structure
Description
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.
CATO supplies (S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-4-(3,4,5-trimethoxyphenyl)butanoic acid (CAS 1260593-23-4), a certified reference material (molecular formula C28H29NO7, MW 491.53 g/mol) for analytical method development and quality control.
(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-4-(3,4,5-trimethoxyphenyl)butanoic acid (C28H29NO7) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
