Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 3-sulfanylidene-2,4-diazaspiro[5.5]undec-8-ene-1,5-dione (CAS 859744-26-6), a certified reference material (molecular formula C9H10N2O2S, MW 210.25 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 3-sulfanylidene-2,4-diazaspiro[5.5]undec-8-ene-1,5-dione is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 210.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 3-sulfanylidene-2,4-diazaspiro[5.5]undec-8-ene-1,5-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.
