Chemical Structure

2-Oxo-2-(p-tolylthio)acetic acid CAS 106871-53-8 chemical structure

Description

2-Oxo-2-(p-tolylthio)acetic acid (C9H8O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

2-Oxo-2-(p-tolylthio)acetic acid (CAS 106871-53-8) is a high-purity analytical reference standard with the molecular formula C9H8O3S and a molecular weight of 196.22 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), 2-Oxo-2-(p-tolylthio)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.
