Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

2-[(1E)-2-(4-Ethylphenyl)ethenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 870717-91-2) is a high-purity analytical reference standard with the molecular formula C16H23BO2 and a molecular weight of 258.16 g/mol.

Based on its molecular formula C16H23BO2, 2-[(1E)-2-(4-Ethylphenyl)ethenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 258.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
