Relating to compounds containing the -SO₂ group, or used to denote the divalent group SO₂ in chemical nomenclature.
Dialectal Variation
British vs American Usage
Differences
Spelling: 'sulphuryl' (UK) vs. 'sulfuryl' (US). The US spelling follows the IUPAC recommendation to use 'f' in all sulphur-related terms.
Connotations
Identical in technical meaning and application.
Frequency
