Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl4-hydroxy-6-oxo-2-(trifluoromethyl)-1h-pyridine-3-carboxylate.
Ethyl4-hydroxy-6-oxo-2-(trifluoromethyl)-1h-pyridine-3-carboxylate (CAS 103900-77-2), molecular formula C9H8F3NO4 and molecular weight 251.16 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H8F3NO4, Ethyl4-hydroxy-6-oxo-2-(trifluoromethyl)-1h-pyridine-3-carboxylate 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 251.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
