Chemical Structure

1-(2-Fluorophenyl)-6-oxo-1,4,5,6-tetrahydropyridazine-3-carboxylic acid CAS 923124-85-0 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 1-(2-Fluorophenyl)-6-oxo-1,4,5,6-tetrahydropyridazine-3-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 236.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

1-(2-Fluorophenyl)-6-oxo-1,4,5,6-tetrahydropyridazine-3-carboxylic acid (CAS 923124-85-0) is a high-purity analytical reference standard with the molecular formula C11H9FN2O3 and a molecular weight of 236.20 g/mol.

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.
