Chemical Structure
Description
The occurrence of 2,2-dimethyl-3-[(4-methylbenzenesulfonyl)oxy]propanal is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,2-dimethyl-3-[(4-methylbenzenesulfonyl)oxy]propanal (CAS 18516-19-3) is a high-purity analytical reference standard with the molecular formula C12H16O4S and a molecular weight of 256.32 g/mol.
2,2-dimethyl-3-[(4-methylbenzenesulfonyl)oxy]propanal (C12H16O4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2,2-dimethyl-3-[(4-methylbenzenesulfonyl)oxy]propanal meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
