Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
n-(2,5-Dimethoxyphenyl)-2-((4,6-dimethylpyrimidin-2-yl)thio)acetamide (CAS 386765-86-2) is a high-purity analytical reference standard with the molecular formula C16H19N3O3S and a molecular weight of 333.41 g/mol.
Structurally, n-(2,5-Dimethoxyphenyl)-2-((4,6-dimethylpyrimidin-2-yl)thio)acetamide (C16H19N3O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 333.41 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).
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.
