Description

Compared with other compounds in its class, the molecular weight of 166.15 g/mol gives 2-(4-fluoro-3-methylphenyl)-2-oxoacetaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(4-fluoro-3-methylphenyl)-2-oxoacetaldehyde (CAS 81593-26-2) is a high-purity analytical reference standard with the molecular formula C9H7FO2 and a molecular weight of 166.15 g/mol.

2-(4-fluoro-3-methylphenyl)-2-oxoacetaldehyde (C9H7FO2) 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, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), 2-(4-fluoro-3-methylphenyl)-2-oxoacetaldehyde meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
