Chemical Structure
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.
CATO supplies 7,7-Difluoro-3,4,6,7,8,9-hexahydropyrazino[1,2-a]indol-1(2H)-one (CAS 1433990-14-7), a certified reference material (molecular formula C11H12F2N2O, MW 226.22 g/mol) for analytical method development and quality control.
Structurally, 7,7-Difluoro-3,4,6,7,8,9-hexahydropyrazino[1,2-a]indol-1(2H)-one (C11H12F2N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 226.22 g/mol, it falls into the medium-molecular-weight range. 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.
