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.
2,4'-Dichloro-5-methyl-[1,1'-biphenyl]-4-carbaldehyde (CAS 2586126-36-3), molecular formula C14H10Cl2O and molecular weight 265.13 g/mol, is a CATO reference standard with documented purity and traceability.
2,4'-Dichloro-5-methyl-[1,1'-biphenyl]-4-carbaldehyde (C14H10Cl2O) contains a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
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.
