Chemical Structure
Description
The molecular framework of 2-Benzyl-1,2,5-thiadiazolidine 1,1-dioxide (C9H12N2O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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).
2-Benzyl-1,2,5-thiadiazolidine 1,1-dioxide (CAS 144432-72-4) is a high-purity analytical reference standard with the molecular formula C9H12N2O2S and a molecular weight of 212.27 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
