Chemical Structure

Pcb No. 165 CAS 74472-46-1 chemical structure

Description

As a certified reference material (CRM), Pcb No. 165 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. 165 (CAS 74472-46-1), a certified reference material (molecular formula C12H4Cl6, MW 360.88 g/mol) for analytical method development and quality control.

Owing to chlorine substitution, an aromatic ring system, Pcb No. 165 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 360.88 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.
