Chemical Structure

1-(3-Fluorophenyl)-1h-pyrazole-5-carboxylic acid CAS 1523072-86-7 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 1-(3-Fluorophenyl)-1h-pyrazole-5-carboxylic acid.

1-(3-Fluorophenyl)-1h-pyrazole-5-carboxylic acid (CAS 1523072-86-7) is a high-purity analytical reference standard with the molecular formula C10H7FN2O2 and a molecular weight of 206.17 g/mol.

Based on its molecular formula C10H7FN2O2, 1-(3-Fluorophenyl)-1h-pyrazole-5-carboxylic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 206.17 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
