Chemical Structure

Pcb No. 41 CAS 52663-59-9 chemical structure

Description

Pcb No. 41 (CAS 52663-59-9) is a high-purity analytical reference standard with the molecular formula C12H6Cl4 and a molecular weight of 291.99 g/mol.

Owing to chlorine substitution, an aromatic ring system, Pcb No. 41 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 291.99 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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

As a certified reference material (CRM), Pcb No. 41 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.
