Chemical Structure

1,4-Dithiane CAS 505-29-3 chemical structure

Description

The occurrence of 1,4-Dithiane is closely related to sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,4-Dithiane (CAS 505-29-3) is a high-purity analytical reference standard with the molecular formula C4H8S2 and a molecular weight of 120.24 g/mol.

Owing to sulfur-containing functionality, 1,4-Dithiane is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 120.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
