Chemical Structure
Description
2-[6-(Dimethylamino)hexa-1,3,5-trienyl]-1,3,3-trimethyl-3h-indolium tetrafluoroborate (CAS 235781-92-7) is a high-purity analytical reference standard with the molecular formula C19H25N2BF4 and a molecular weight of 368.22 g/mol.
Structurally, 2-[6-(Dimethylamino)hexa-1,3,5-trienyl]-1,3,3-trimethyl-3h-indolium tetrafluoroborate (C19H25N2BF4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.5, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 368.22 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
