{[(4-Methylphenyl)carbonothioyl]thio}acetic acid CAS 57149-19-6

Description

{[(4-Methylphenyl)carbonothioyl]thio}acetic acid (CAS 57149-19-6), molecular formula C10H10O2S2 and molecular weight 226.32 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of {[(4-Methylphenyl)carbonothioyl]thio}acetic acid (C10H10O2S2) 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 its high hydrophobicity (logP), 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), {[(4-Methylphenyl)carbonothioyl]thio}acetic 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.
