Chemical Structure

Tetrahydro-2H-thiopyran 1-oxide CAS 4988-34-5 chemical structure

Description

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.

Tetrahydro-2H-thiopyran 1-oxide (CAS 4988-34-5) is a high-purity analytical reference standard with the molecular formula C5H10OS and a molecular weight of 118.20 g/mol.

The molecular framework of Tetrahydro-2H-thiopyran 1-oxide (C5H10OS) 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.

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.
