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 4-(2-Fluoro-3-iodophenyl)-1-methyl-1H-pyrazole.
4-(2-Fluoro-3-iodophenyl)-1-methyl-1H-pyrazole (CAS 2434716-84-2), molecular formula C10H8FIN2 and molecular weight 302.09 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H8FIN2, 4-(2-Fluoro-3-iodophenyl)-1-methyl-1H-pyrazole contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 302.09 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.
