Pcb No. 207 CAS 52663-79-3 chemical structure

Description

CATO supplies Pcb No. 207 (CAS 52663-79-3), a certified reference material (molecular formula C12HCl9, MW 464.21 g/mol) for analytical method development and quality control.

The molecular framework of Pcb No. 207 (C12HCl9) is characterized by chlorine substitution, an aromatic ring 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), Pcb No. 207 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.
