Chemical Structure
Description
Structurally, 5,6-dimethyl-2-[(morpholin-4-yl)methyl]thieno[2,3-d]pyrimidine-4-thiol (C13H25N3OS2) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 303.49 g/mol, it falls into the moderately-high-molecular-weight range. 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).
5,6-dimethyl-2-[(morpholin-4-yl)methyl]thieno[2,3-d]pyrimidine-4-thiol (CAS 730976-46-2), molecular formula C13H25N3OS2 and molecular weight 303.49 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
