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.
7,7-Bis(2-methyl-1-octyl-1H-indol-3-yl)furo[3,4-b]pyridin-5(7H)-one (CAS 89923-59-1) is a high-purity analytical reference standard with the molecular formula C41H51N3O2 and a molecular weight of 617.86 g/mol.
Structurally, 7,7-Bis(2-methyl-1-octyl-1H-indol-3-yl)furo[3,4-b]pyridin-5(7H)-one (C41H51N3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 617.86 g/mol, it falls into the high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
