2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-((3,7-dioxo-1,9-diphenyl-2,8-dioxa-4,6-diazanonan-5-ylidene)amino)propanoic acid CAS 2044703-23-1

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.

2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-((3,7-dioxo-1,9-diphenyl-2,8-dioxa-4,6-diazanonan-5-ylidene)amino)propanoic acid (CAS 2044703-23-1) is a high-purity analytical reference standard with the molecular formula C35H32N4O8 and a molecular weight of 636.65 g/mol.

Based on its molecular formula C35H32N4O8, 2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-((3,7-dioxo-1,9-diphenyl-2,8-dioxa-4,6-diazanonan-5-ylidene)amino)propanoic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 636.65 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
