Chemical Structure
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.
2-Chloro-1-(4-chloro-3-fluorophenyl)ethan-1-one (CAS 860029-79-4), molecular formula C8H5Cl2FO and molecular weight 207.03 g/mol, is a CATO reference standard with documented purity and traceability.
2-Chloro-1-(4-chloro-3-fluorophenyl)ethan-1-one (C8H5Cl2FO) contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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).
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.
