5-(3-Fluorophenyl)-2-methyl-1H-pyrrole-3-carboxylic acid CAS 1521791-99-0

Description

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.

5-(3-Fluorophenyl)-2-methyl-1H-pyrrole-3-carboxylic acid (CAS 1521791-99-0) is a high-purity analytical reference standard with the molecular formula C12H10FNO2 and a molecular weight of 219.21 g/mol.

5-(3-Fluorophenyl)-2-methyl-1H-pyrrole-3-carboxylic acid (C12H10FNO2) 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, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

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.
