5-Methoxy-3-methylthiopyridine CAS 98627-13-5

Description

Compared with other compounds in its class, the molecular weight of 155.22 g/mol gives 5-Methoxy-3-methylthiopyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Methoxy-3-methylthiopyridine (CAS 98627-13-5) is a high-purity analytical reference standard with the molecular formula C7H9NOS and a molecular weight of 155.22 g/mol.

Based on its molecular formula C7H9NOS, 5-Methoxy-3-methylthiopyridine contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 155.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 5-Methoxy-3-methylthiopyridine 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.
