2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-4-(methylselanyl)butanoic acid CAS 1369531-99-6

Description

The molecular framework of 2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-4-(methylselanyl)butanoic acid (C20H21NO4Se) 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).

2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-4-(methylselanyl)butanoic acid (CAS 1369531-99-6), molecular formula C20H21NO4Se and molecular weight 418.35 g/mol, is a CATO reference standard with documented purity and traceability.

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.
