Chemical Structure

S-Methyl-d3-thioacetaminophen CAS 1215669-56-9 chemical structure

Description

The molecular framework of S-Methyl-d3-thioacetaminophen (C9H8D3NO2S) is characterized by deuterium isotope labeling, 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).

CATO supplies S-Methyl-d3-thioacetaminophen (CAS 1215669-56-9), a certified reference material (molecular formula C9H8D3NO2S, MW 200.27 g/mol) for analytical method development and quality control.

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-d3-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.
