Chemical Structure

PCB No. 11 CAS 2050-67-1 chemical structure

Description

As a certified reference material (CRM), PCB No. 11 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. 11 (CAS 2050-67-1), a certified reference material (molecular formula C12H8Cl2, MW 223.10 g/mol) for analytical method development and quality control.

Owing to chlorine substitution, an aromatic ring system, PCB No. 11 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 223.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
