Chemical Structure

Sodium S-(p-tolyl) sulfurothioate CAS 38078-55-6 chemical structure

Description

The occurrence of Sodium S-(p-tolyl) sulfurothioate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Sodium S-(p-tolyl) sulfurothioate (CAS 38078-55-6), molecular formula C7H7O3S2Na and molecular weight 226.24 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Sodium S-(p-tolyl) sulfurothioate (C7H7O3S2Na) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 S-(p-tolyl) sulfurothioate 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.
