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-(5-bromopyridin-2-yl)-5-methylpyrazole-4-carboxylate.
Ethyl 1-(5-bromopyridin-2-yl)-5-methylpyrazole-4-carboxylate (CAS 1150164-72-9), molecular formula C12H12BrN3O2 and molecular weight 310.15 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H12BrN3O2, Ethyl 1-(5-bromopyridin-2-yl)-5-methylpyrazole-4-carboxylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 310.15 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.
