Chemical Structure
Description
As a certified reference material (CRM), 4-chloro-1λ⁶-thiane-1,1-dione 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.
4-chloro-1λ⁶-thiane-1,1-dione (CAS 38690-85-6), molecular formula C5H9ClO2S and molecular weight 168.64 g/mol, is a CATO reference standard with documented purity and traceability.
4-chloro-1λ⁶-thiane-1,1-dione (C5H9ClO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
