4-(4-Fluoro-3-methylphenyl)butanoic acid CAS 331-43-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(4-Fluoro-3-methylphenyl)butanoic acid.

4-(4-Fluoro-3-methylphenyl)butanoic acid (CAS 331-43-1) is a high-purity analytical reference standard with the molecular formula C11H13FO2 and a molecular weight of 196.22 g/mol.

4-(4-Fluoro-3-methylphenyl)butanoic acid (C11H13FO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
