Chemical Structure

Tetrahydrofurfurylsodiumthiosulfate CAS 77339-73-2 chemical structure

Description

The occurrence of Tetrahydrofurfurylsodiumthiosulfate is closely related to a carbohydrate-derived structure, a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Tetrahydrofurfurylsodiumthiosulfate (CAS 77339-73-2) is a high-purity analytical reference standard with the molecular formula H2O3S2C5H9NaO and a molecular weight of 222.25 g/mol.

Based on its molecular formula H2O3S2C5H9NaO, Tetrahydrofurfurylsodiumthiosulfate contains a carbohydrate-derived structure, a sulfone group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 222.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
