Chemical Structure

4,4,5,5-Tetramethyl-2-(8-phenylphenanthren-2-yl)-1,3,2-dioxaborolane CAS CATO-CIM-105129 chemical structure

Description

The occurrence of 4,4,5,5-Tetramethyl-2-(8-phenylphenanthren-2-yl)-1,3,2-dioxaborolane is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4,4,5,5-Tetramethyl-2-(8-phenylphenanthren-2-yl)-1,3,2-dioxaborolane (CAS CATO-CIM-105129) is a high-purity analytical reference standard with the molecular formula C26H25BO2 and a molecular weight of 380.29 g/mol.

The molecular framework of 4,4,5,5-Tetramethyl-2-(8-phenylphenanthren-2-yl)-1,3,2-dioxaborolane (C26H25BO2) is characterized by a steroid core, a hydroxyl group, an ether linkage. 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).

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.
