Chemical Structure
Description
Based on its molecular formula Cl3SbC8H20O4Si, Silicic acid (H4SiO4), tetraethyl ester, polymer with trichlorostibine 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 436.44 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.
CATO supplies Silicic acid (H4SiO4), tetraethyl ester, polymer with trichlorostibine (CAS 135929-41-8), a certified reference material (molecular formula Cl3SbC8H20O4Si, MW 436.44 g/mol) for analytical method development and quality control.
