Description

Compared with other compounds in its class, the molecular weight of 250.23 g/mol gives [1-(4-Fluorophenyl)-5-hydroxy-3-methyl-1H-pyrazol-4-yl]acetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

[1-(4-Fluorophenyl)-5-hydroxy-3-methyl-1H-pyrazol-4-yl]acetic acid (CAS 1306739-27-4), molecular formula C12H11FN2O3 and molecular weight 250.23 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of [1-(4-Fluorophenyl)-5-hydroxy-3-methyl-1H-pyrazol-4-yl]acetic acid (C12H11FN2O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
