Chemical Structure
Description
The molecular framework of 2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-(6-chloro-1H-indol-3-yl)propanoic acid (C26H21ClN2O4) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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 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).
2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-(6-chloro-1H-indol-3-yl)propanoic acid (CAS 1219168-45-2) is a high-purity analytical reference standard with the molecular formula C26H21ClN2O4 and a molecular weight of 460.91 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
