Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Benzyl-3-({[(9h-fluoren-9-yl)methoxy]carbonyl}amino)propanoic acid.
2-Benzyl-3-({[(9h-fluoren-9-yl)methoxy]carbonyl}amino)propanoic acid (CAS 683217-58-5) is a high-purity analytical reference standard with the molecular formula C25H23NO4 and a molecular weight of 401.45 g/mol.
2-Benzyl-3-({[(9h-fluoren-9-yl)methoxy]carbonyl}amino)propanoic acid (C25H23NO4) contains a flavonoid core, 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).
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.
