Chemical Structure
Description
The occurrence of 4,4-Dioxo-1,4-oxathiane is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4,4-Dioxo-1,4-oxathiane (CAS 107-61-9), molecular formula C4H8O3S and molecular weight 136.17 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 4,4-Dioxo-1,4-oxathiane is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 136.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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), 4,4-Dioxo-1,4-oxathiane 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.
