Chemical Structure
Description
The occurrence of 10,15-Dihydro-5,5,10,10,15,15-hexamethyl-5H-tribenzo[a,f,k]trindene is closely related to a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
10,15-Dihydro-5,5,10,10,15,15-hexamethyl-5H-tribenzo[a,f,k]trindene (CAS 597554-76-2) is a high-purity analytical reference standard with the molecular formula C33H30 and a molecular weight of 426.59 g/mol.
The molecular framework of 10,15-Dihydro-5,5,10,10,15,15-hexamethyl-5H-tribenzo[a,f,k]trindene (C33H30) is characterized by a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
