5,5-Bis(benzylthio)pentane-1,2,3,4-tetraol CAS 64780-60-5

Description

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

5,5-Bis(benzylthio)pentane-1,2,3,4-tetraol (CAS 64780-60-5) is a high-purity analytical reference standard with the molecular formula C19H24O4S2 and a molecular weight of 380.52 g/mol.

Structurally, 5,5-Bis(benzylthio)pentane-1,2,3,4-tetraol (C19H24O4S2) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 380.52 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
