2-Hydroxy-4-trifluoromethyl-pyrimidine-5-carboxylic acid ethyl ester; hydrate (CAS 1208081-14-4) is a high-purity analytical reference standard with the molecular formula C8H7F3N2O3H2O and a molecular weight of 254.16 g/mol.
Based on its molecular formula C8H7F3N2O3H2O, 2-Hydroxy-4-trifluoromethyl-pyrimidine-5-carboxylic acid ethyl ester; hydrate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 254.16 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).
As a certified reference material (CRM), 2-Hydroxy-4-trifluoromethyl-pyrimidine-5-carboxylic acid ethyl ester; hydrate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
