Chemical Structure

Sodium 4-ethylbenzene-1-sulfinate CAS 89520-66-1 chemical structure

Description

Based on its molecular formula C8H9O2SNa, Sodium 4-ethylbenzene-1-sulfinate 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 192.21 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).

Sodium 4-ethylbenzene-1-sulfinate (CAS 89520-66-1), molecular formula C8H9O2SNa and molecular weight 192.21 g/mol, is a CATO reference standard with documented purity and traceability.

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), Sodium 4-ethylbenzene-1-sulfinate 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.
