Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,2,3,6,8-Pentachloronaphthalene (CAS 150224-23-0), molecular formula C10H3Cl5 and molecular weight 300.40 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,2,3,6,8-Pentachloronaphthalene (C10H3Cl5) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 1,2,3,6,8-Pentachloronaphthalene 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.
