Description
CATO supplies N-(3-Chloro-4-Fluorophenyl)-2-[(1,4-Dihydro-5,6-Dimethyl-4-Oxothieno[2,3-d]Pyrimidin-2-ylThio]-Acetamide (CAS 606108-58-1), a certified reference material (molecular formula C16H13ClFN3O2S2, MW 397.87 g/mol) for analytical method development and quality control.
Structurally, N-(3-Chloro-4-Fluorophenyl)-2-[(1,4-Dihydro-5,6-Dimethyl-4-Oxothieno[2,3-d]Pyrimidin-2-ylThio]-Acetamide (C16H13ClFN3O2S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 397.87 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).
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.
