Chemical Structure
Description
1-(2,4-Dichlorophenyl)cyclopropanecarboxylic Acid (CAS 84604-70-6) is a high-purity analytical reference standard with the molecular formula C10H8Cl2O2 and a molecular weight of 231.08 g/mol.
1-(2,4-Dichlorophenyl)cyclopropanecarboxylic Acid (C10H8Cl2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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.
