Chemical Structure

2,2-Dichloro-1,4-dioxane CAS 57253-41-5 chemical structure

Description

2,2-Dichloro-1,4-dioxane (CAS 57253-41-5) is a high-purity analytical reference standard with the molecular formula C4H6Cl2O2 and a molecular weight of 157.00 g/mol.

Based on its molecular formula C4H6Cl2O2, 2,2-Dichloro-1,4-dioxane contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 157.00 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
