(2R,3S,4S)-5,5-bis(ethylthio)pentane-1,2,3,4-tetraol CAS 6838-08-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2R,3S,4S)-5,5-bis(ethylthio)pentane-1,2,3,4-tetraol.

(2R,3S,4S)-5,5-bis(ethylthio)pentane-1,2,3,4-tetraol (CAS 6838-08-0) is a high-purity analytical reference standard with the molecular formula C9H20O4S2 and a molecular weight of 256.38 g/mol.

Based on its molecular formula C9H20O4S2, (2R,3S,4S)-5,5-bis(ethylthio)pentane-1,2,3,4-tetraol contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 256.38 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.
