2,3,4,5,6-Pentachloro-p-terphenyl CAS 61577-01-3

Description

The occurrence of 2,3,4,5,6-Pentachloro-p-terphenyl is closely related to chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2,3,4,5,6-Pentachloro-p-terphenyl (CAS 61577-01-3), a certified reference material (molecular formula C18H9Cl5, MW 402.53 g/mol) for analytical method development and quality control.

The molecular framework of 2,3,4,5,6-Pentachloro-p-terphenyl (C18H9Cl5) is characterized by 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. 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), 2,3,4,5,6-Pentachloro-p-terphenyl 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.
