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.
S-(1,1-dioxidotetrahydrothiophen-3-yl) ethanethioate (CAS 201990-25-2) is a high-purity analytical reference standard with the molecular formula C6H10O3S2 and a molecular weight of 194.27 g/mol.
The molecular framework of S-(1,1-dioxidotetrahydrothiophen-3-yl) ethanethioate (C6H10O3S2) is characterized by a sulfone group, a carboxylic acid group, 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.
