Chemical Structure

3,4-Difluoro-α-methylbenzenepropanoic acid CAS 32004-56-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 200.18 g/mol gives 3,4-Difluoro-α-methylbenzenepropanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3,4-Difluoro-α-methylbenzenepropanoic acid (CAS 32004-56-1), molecular formula C10H10F2O2 and molecular weight 200.18 g/mol, is a CATO reference standard with documented purity and traceability.

3,4-Difluoro-α-methylbenzenepropanoic acid (C10H10F2O2) 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. 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.
