Chemical Structure

Pcb No. 34 CAS 37680-68-5 chemical structure

Description

Pcb No. 34 (CAS 37680-68-5) is a high-purity analytical reference standard with the molecular formula C12H7Cl3 and a molecular weight of 257.54 g/mol.

The molecular framework of Pcb No. 34 (C12H7Cl3) is characterized by chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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. 34 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.
