Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 264.75 g/mol gives 4-Chloro-p-terphenyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Chloro-p-terphenyl (CAS 1762-83-0), molecular formula C18H13Cl and molecular weight 264.75 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Chloro-p-terphenyl (C18H13Cl) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures 4-Chloro-p-terphenyl under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
