Chemical Structure
Description
CATO supplies 4-(2-Chloropyrido[3,2-d]pyrimidin-4-yl)thiomorpholine 1,1-dioxide (CAS 39551-64-9), a certified reference material (molecular formula C11H11ClN4O2S, MW 298.75 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, chlorine substitution, 4-(2-Chloropyrido[3,2-d]pyrimidin-4-yl)thiomorpholine 1,1-dioxide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 298.75 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).
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-(2-Chloropyrido[3,2-d]pyrimidin-4-yl)thiomorpholine 1,1-dioxide 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.
