2,3,5,6-Tetrachloro-p-terphenyl CAS 61576-99-6

Description

The occurrence of 2,3,5,6-Tetrachloro-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 2,3,5,6-Tetrachloro-p-terphenyl (CAS 61576-99-6), a certified reference material (molecular formula C18H10Cl4, MW 368.08 g/mol) for analytical method development and quality control.

Based on its molecular formula C18H10Cl4, 2,3,5,6-Tetrachloro-p-terphenyl contains chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 368.08 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 2,3,5,6-Tetrachloro-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.
