Chemical Structure

1,3-Dithiane CAS 505-23-7 chemical structure

Description

1,3-Dithiane (CAS 505-23-7), molecular formula C4H8S2 and molecular weight 120.24 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,3-Dithiane (C4H8S2) is characterized by sulfur-containing functionality. 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.

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.
