Chemical Structure
Description
The molecular framework of 4-[(4-Nitrophenyl)sulfanyl]phenylboronic acid (C12H10BNO4S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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).
4-[(4-Nitrophenyl)sulfanyl]phenylboronic acid (CAS 2377605-69-9) is a high-purity analytical reference standard with the molecular formula C12H10BNO4S and a molecular weight of 275.09 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.
As a certified reference material (CRM), 4-[(4-Nitrophenyl)sulfanyl]phenylboronic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
