Chemical Structure

Perbromothiophene 1,1-dioxide CAS 72524-90-4 chemical structure

Description

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.

Perbromothiophene 1,1-dioxide (CAS 72524-90-4) is a high-purity analytical reference standard with the molecular formula C4Br4O2S and a molecular weight of 431.72 g/mol.

The molecular framework of Perbromothiophene 1,1-dioxide (C4Br4O2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
