Chemical Structure
Description
The occurrence of (Difluoro(trimethylsilyl)methyl)phosphonic acid is closely related to a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(Difluoro(trimethylsilyl)methyl)phosphonic acid (CAS 913263-04-4) is a high-purity analytical reference standard with the molecular formula C4H11F2O3PSi and a molecular weight of 204.18 g/mol.
Owing to a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, (Difluoro(trimethylsilyl)methyl)phosphonic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 204.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
