Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 423.42 g/mol gives 2,2',3,3',4,4',5-Heptachlorodiphenyl Ether distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2,2',3,3',4,4',5-Heptachlorodiphenyl Ether (CAS 71585-40-5), a certified reference material (molecular formula C12H15Cl7O, MW 423.42 g/mol) for analytical method development and quality control.
The molecular framework of 2,2',3,3',4,4',5-Heptachlorodiphenyl Ether (C12H15Cl7O) is characterized by a hydroxyl group, an ether linkage, chlorine substitution. 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. 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), 2,2',3,3',4,4',5-Heptachlorodiphenyl Ether 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.
