5-Chloro-3-(3,5-dichlorophenyl)benzoic acid CAS 1261914-46-8

Description

Compared with other compounds in its class, the molecular weight of 301.55 g/mol gives 5-Chloro-3-(3,5-dichlorophenyl)benzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Chloro-3-(3,5-dichlorophenyl)benzoic acid (CAS 1261914-46-8) is a high-purity analytical reference standard with the molecular formula C13H7Cl3O2 and a molecular weight of 301.55 g/mol.

Structurally, 5-Chloro-3-(3,5-dichlorophenyl)benzoic acid (C13H7Cl3O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring 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 301.55 g/mol, it falls into the moderately-high-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.

As a certified reference material (CRM), 5-Chloro-3-(3,5-dichlorophenyl)benzoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
