Description

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.

4,4,5,5-Tetramethyl-2-[2-(methylsulfonyl)phenyl]-1,3,2-dioxaborolane (CAS 879648-22-3), molecular formula C13H19BO4S and molecular weight 282.16 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4,4,5,5-Tetramethyl-2-[2-(methylsulfonyl)phenyl]-1,3,2-dioxaborolane (C13H19BO4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 282.16 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
