Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-Chloro-6-(2,2,2-trifluoroethyl)thieno[3,2-d]pyrimidine (CAS 2102553-51-3) is a high-purity analytical reference standard with the molecular formula C8H4ClF3N2S and a molecular weight of 252.64 g/mol.
Structurally, 4-Chloro-6-(2,2,2-trifluoroethyl)thieno[3,2-d]pyrimidine (C8H4ClF3N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 252.64 g/mol, it falls into the medium-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.
