Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 300.24 g/mol gives Ethyl 5-amino-1-[5-(trifluoromethyl)pyridin-2-yl]-1h-pyrazole-4-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ethyl 5-amino-1-[5-(trifluoromethyl)pyridin-2-yl]-1h-pyrazole-4-carboxylate (CAS 107748-84-5), a certified reference material (molecular formula C12H11F3N4O2, MW 300.24 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Ethyl 5-amino-1-[5-(trifluoromethyl)pyridin-2-yl]-1h-pyrazole-4-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 300.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
