5-(4-Fluorophenyl)-3-(4-methoxyphenyl)-1H-pyrazole CAS 37613-37-9

Description

The occurrence of 5-(4-Fluorophenyl)-3-(4-methoxyphenyl)-1H-pyrazole is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-(4-Fluorophenyl)-3-(4-methoxyphenyl)-1H-pyrazole (CAS 37613-37-9) is a high-purity analytical reference standard with the molecular formula C16H13FN2O and a molecular weight of 268.29 g/mol.

5-(4-Fluorophenyl)-3-(4-methoxyphenyl)-1H-pyrazole (C16H13FN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
