Description

Structurally, (4-((4-Ethylpiperazin-1-yl)sulfonyl)-3,5-dimethylphenyl)boronic acid (C14H23BN2O4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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 326.22 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

(4-((4-Ethylpiperazin-1-yl)sulfonyl)-3,5-dimethylphenyl)boronic acid (CAS 1704067-32-2) is a high-purity analytical reference standard with the molecular formula C14H23BN2O4S and a molecular weight of 326.22 g/mol.

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.
