Chemical Structure
Description
The occurrence of 6-(2-Fluorophenyl)-2,3-dihydro-4H-indeno[1',2':4,5]pyrimido[2,1-b][1,3]thiazine-4,7(6H)-dione is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6-(2-Fluorophenyl)-2,3-dihydro-4H-indeno[1',2':4,5]pyrimido[2,1-b][1,3]thiazine-4,7(6H)-dione (CAS 860788-38-1), molecular formula C20H13FN2O2S and molecular weight 364.39 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C20H13FN2O2S, 6-(2-Fluorophenyl)-2,3-dihydro-4H-indeno[1',2':4,5]pyrimido[2,1-b][1,3]thiazine-4,7(6H)-dione contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 364.39 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
