Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(3',5'-Dichloro-[1,1'-biphenyl]-2-yl)aceticacid (CAS 669713-79-5), molecular formula C14H10Cl2O2 and molecular weight 281.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(3',5'-Dichloro-[1,1'-biphenyl]-2-yl)aceticacid (C14H10Cl2O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
