Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-(1-Oxa-4-thia-8-azaspiro[4.5]decan-8-yl)-2-(thiophen-3-yl)ethan-1-one (CAS 1797617-35-6) is a high-purity analytical reference standard with the molecular formula C13H17NO2S2 and a molecular weight of 283.41 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 1-(1-Oxa-4-thia-8-azaspiro[4.5]decan-8-yl)-2-(thiophen-3-yl)ethan-1-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 283.41 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), 1-(1-Oxa-4-thia-8-azaspiro[4.5]decan-8-yl)-2-(thiophen-3-yl)ethan-1-one 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.
