Chemical Structure
Description
Based on its molecular formula C6H14Cl4OSi2, 1,3-Bis(dichloromethyl)-1,1,3,3-tetramethyldisiloxane contains 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 300.16 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.
1,3-Bis(dichloromethyl)-1,1,3,3-tetramethyldisiloxane (CAS 2943-70-6) is a high-purity analytical reference standard with the molecular formula C6H14Cl4OSi2 and a molecular weight of 300.16 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.
