1-(5,5-Difluoro-7,9-dimethyl-5H-5lambda4,6lambda4-dipyrrolo[1,2-c:2',1'-f][1,3,2]diazaborinin-3-yl)-3-oxo-7,10,13,16-tetraoxa-4-azanonadecan-19-oate (CAS 2288761-92-0) is a high-purity analytical reference standard with the molecular formula C25H35BF2N3O7 and a molecular weight of 538.37 g/mol.
The molecular framework of 1-(5,5-Difluoro-7,9-dimethyl-5H-5lambda4,6lambda4-dipyrrolo[1,2-c:2',1'-f][1,3,2]diazaborinin-3-yl)-3-oxo-7,10,13,16-tetraoxa-4-azanonadecan-19-oate (C25H35BF2N3O7) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
