Benzenesulfonic Acid Impurity 9 CAS 735200-57-4

Description

Compared with other compounds in its class, the molecular weight of 218.23 g/mol gives Benzenesulfonic Acid Impurity 9 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Benzenesulfonic Acid Impurity 9 (CAS 735200-57-4) is a high-purity analytical reference standard with the molecular formula C8H10O5S and a molecular weight of 218.23 g/mol.

Based on its molecular formula C8H10O5S, Benzenesulfonic Acid Impurity 9 contains a sulfone group, 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 218.23 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.

As a certified reference material (CRM), Benzenesulfonic Acid Impurity 9 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.
