PCB No. 7 CAS 33284-50-3 chemical structure

Description

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

PCB No. 7 (CAS 33284-50-3) is a high-purity analytical reference standard with the molecular formula C12H8Cl2 and a molecular weight of 223.10 g/mol.

Owing to chlorine substitution, an aromatic ring system, PCB No. 7 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO manufactures PCB No. 7 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
