2-Methyldihydro-2H-thiopyran-3(4H)-one CAS 69261-29-6

Description

The occurrence of 2-Methyldihydro-2H-thiopyran-3(4H)-one is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Methyldihydro-2H-thiopyran-3(4H)-one (CAS 69261-29-6) is a high-purity analytical reference standard with the molecular formula C6H10OS and a molecular weight of 130.21 g/mol.

The molecular framework of 2-Methyldihydro-2H-thiopyran-3(4H)-one (C6H10OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
