Chemical Structure

Pcb No. 123 CAS 65510-44-3 chemical structure

Description

As a certified reference material (CRM), Pcb No. 123 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.

CATO supplies Pcb No. 123 (CAS 65510-44-3), a certified reference material (molecular formula C12H5Cl5, MW 326.43 g/mol) for analytical method development and quality control.

The molecular framework of Pcb No. 123 (C12H5Cl5) 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
