Description
Compared with other compounds in its class, the molecular weight of 283.35 g/mol gives tert-Butyl 4-oxo-2-thioxo-2,3,4,5,6,8-hexahydropyrido[3,4-d]pyrimidine-7(1H)-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
tert-Butyl 4-oxo-2-thioxo-2,3,4,5,6,8-hexahydropyrido[3,4-d]pyrimidine-7(1H)-carboxylate (CAS 2383244-62-8), molecular formula C12H17N3O3S and molecular weight 283.35 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, tert-Butyl 4-oxo-2-thioxo-2,3,4,5,6,8-hexahydropyrido[3,4-d]pyrimidine-7(1H)-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 283.35 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.
