Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 154.23 g/mol gives 1-Methyl-3-(methylsulfinyl)benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Methyl-3-(methylsulfinyl)benzene (CAS 13150-71-5), molecular formula C8H10OS and molecular weight 154.23 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, 1-Methyl-3-(methylsulfinyl)benzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 154.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 1-Methyl-3-(methylsulfinyl)benzene 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.
