8-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-4H-chromen-4-one CAS 1655495-95-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 272.10 g/mol gives 8-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-4H-chromen-4-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

8-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-4H-chromen-4-one (CAS 1655495-95-6), molecular formula C15H17BO4 and molecular weight 272.10 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, 8-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-4H-chromen-4-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 272.10 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.
