Chemical Structure

S-Methyl-3-thioacetaminophen CAS 37398-23-5 chemical structure

Description

The occurrence of S-Methyl-3-thioacetaminophen is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies S-Methyl-3-thioacetaminophen (CAS 37398-23-5), a certified reference material (molecular formula C9H11NO2S, MW 197.25 g/mol) for analytical method development and quality control.

The molecular framework of S-Methyl-3-thioacetaminophen (C9H11NO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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), S-Methyl-3-thioacetaminophen 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.
