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 Ethyl 1-(3-chloro-5-(trifluoromethyl)pyridin-2-yl)-1H-pyrrole-2-carboxylate.
Ethyl 1-(3-chloro-5-(trifluoromethyl)pyridin-2-yl)-1H-pyrrole-2-carboxylate (CAS 321430-87-9) is a high-purity analytical reference standard with the molecular formula C13H10ClF3N2O2 and a molecular weight of 318.68 g/mol.
Based on its molecular formula C13H10ClF3N2O2, Ethyl 1-(3-chloro-5-(trifluoromethyl)pyridin-2-yl)-1H-pyrrole-2-carboxylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 318.68 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
