Chemical Structure
Description
272-24-2 Thieno[2,3-d]pyrimidine DTXSID90481268 (CAS 272-24-2), molecular formula C6H4N2S and molecular weight 136.17 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, sulfur-containing functionality, an aromatic ring system, 272-24-2 Thieno[2,3-d]pyrimidine DTXSID90481268 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 136.17 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.
