Chemical Structure
Description
The molecular framework of Dimethyl(1,3,5-trithian-2-yl)phosphine oxide (C5H11OPS3) is characterized by sulfur-containing functionality, organophosphorus functionality, 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.
Dimethyl(1,3,5-trithian-2-yl)phosphine oxide (CAS 343871-57-8) is a high-purity analytical reference standard with the molecular formula C5H11OPS3 and a molecular weight of 214.31 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.
