Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 287.37 g/mol gives 1,3-Bis(3-chloropropyl)tetramethyldisiloxane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1,3-Bis(3-chloropropyl)tetramethyldisiloxane (CAS 18132-72-4), a certified reference material (molecular formula C10H24Cl2OSi2, MW 287.37 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H24Cl2OSi2, 1,3-Bis(3-chloropropyl)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 287.37 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.
