PCB No. 166 CAS 41411-63-6 chemical structure

Description

PCB No. 166 (CAS 41411-63-6), molecular formula C12H4Cl6 and molecular weight 360.88 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to chlorine substitution, an aromatic ring system, PCB No. 166 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).

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

CATO manufactures PCB No. 166 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.
