2-(2-[5-[2-(3,3-Dimethyl-1-phenyl-1,3-dihydro-2H-indol-2-ylidene)ethylidene]-2H-pyran-3(6H)-yl]ethenyl)-3,3-dimethyl-1-phenyl-3H-indolium tetrafluoroborate CAS 262607-26-1

Description

2-(2-[5-[2-(3,3-Dimethyl-1-phenyl-1,3-dihydro-2H-indol-2-ylidene)ethylidene]-2H-pyran-3(6H)-yl]ethenyl)-3,3-dimethyl-1-phenyl-3H-indolium tetrafluoroborate (CAS 262607-26-1) is a high-purity analytical reference standard with the molecular formula C41H39N2OBF4 and a molecular weight of 662.58 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 2-(2-[5-[2-(3,3-Dimethyl-1-phenyl-1,3-dihydro-2H-indol-2-ylidene)ethylidene]-2H-pyran-3(6H)-yl]ethenyl)-3,3-dimethyl-1-phenyl-3H-indolium tetrafluoroborate is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 662.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

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.
