4-Sulfothiacalix[4]arene Sodium Salt CAS 211561-04-5

Description

The occurrence of 4-Sulfothiacalix[4]arene Sodium Salt is closely related to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Sulfothiacalix[4]arene Sodium Salt (CAS 211561-04-5) is a high-purity analytical reference standard with the molecular formula C24H12O12S8Na and a molecular weight of 771.82 g/mol.

The molecular framework of 4-Sulfothiacalix[4]arene Sodium Salt (C24H12O12S8Na) is characterized by a flavonoid core, a sulfone 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
