What it is Filled
Diethyl sulfoxide is an organosulfur compound with the structure (C₂H₅)₂S=O, in which two ethyl groups are bonded to the sulfur atom of a sulfoxide group.
In scope
- Molecular identity, synonyms and chemical registry identifiers
- Sample composition, assay basis, water content and impurities
- Physical state and measured properties under stated conditions
- Chemical stability and compatibility for a specified use
- Substance-specific hazard evidence and jurisdiction-dependent status
Out of scope
- Manufacturing processes and their equipment
- Commercial formulations containing diethylsulfoxide as one component
- Diethyl sulfide, diethyl sulfone and dimethyl sulfoxide as independently modelled substances
- Coordination complexes incorporating diethylsulfoxide
- Laboratory procedures, facility controls and waste treatment processes
Why it exists Filled
Enable an agent to identify diethylsulfoxide, assess the condition and suitability of a sample, and determine which handling or use decisions have adequate evidence.
Distinguishing features Filled
- Match the identity to CAS 70-29-1, PubChem CID 6263 and EC 200-732-2; verify the structure as CCS(=O)CC and formula C4H10OS. These identifiers are reported by [PubChem](https://pubchem.ncbi.nlm.nih.gov/compound/Diethyl-sulfoxide).
- Confirm two ethyl groups attached directly to sulfur; this distinguishes diethylsulfoxide from dimethyl sulfoxide and from constitutional isomers sharing its molecular formula.
- Confirm a sulfoxide group with one oxygen at sulfur; distinguish the material from the corresponding sulfide and sulfone.
- Require analytical evidence of identity and composition when distinguishing a neat diethylsulfoxide sample from a solution or reaction mixture containing it.
