Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
12-Amino-6,7,8,9-tetrachloro-1,2,3,4-tetrahydro-4a,10a-(epithioetheno)dibenzo[b,e][1,4]dioxine-11-carboxamide (CAS 924967-53-3), molecular formula C15H12Cl4N2O3S and molecular weight 442.14 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 12-Amino-6,7,8,9-tetrachloro-1,2,3,4-tetrahydro-4a,10a-(epithioetheno)dibenzo[b,e][1,4]dioxine-11-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 442.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 12-Amino-6,7,8,9-tetrachloro-1,2,3,4-tetrahydro-4a,10a-(epithioetheno)dibenzo[b,e][1,4]dioxine-11-carboxamide 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.
