Pcb No. 21 CAS 55702-46-0 chemical structure

Description

CATO manufactures Pcb No. 21 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.

CATO supplies Pcb No. 21 (CAS 55702-46-0), a certified reference material (molecular formula C12H7Cl3, MW 257.54 g/mol) for analytical method development and quality control.

Pcb No. 21 (C12H7Cl3) contains chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
