2-(3',5'-Dichloro-[1,1'-biphenyl]-4-yl)aceticacid CAS 669713-81-9

Description

Compared with other compounds in its class, the molecular weight of 281.13 g/mol gives 2-(3',5'-Dichloro-[1,1'-biphenyl]-4-yl)aceticacid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(3',5'-Dichloro-[1,1'-biphenyl]-4-yl)aceticacid (CAS 669713-81-9), molecular formula C14H10Cl2O2 and molecular weight 281.13 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-(3',5'-Dichloro-[1,1'-biphenyl]-4-yl)aceticacid (C14H10Cl2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 281.13 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
