Chemical Structure
Description
As a certified reference material (CRM), Buta-1,3-diene-1,2,3,4-tetrayltetrabenzene 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.
CATO supplies Buta-1,3-diene-1,2,3,4-tetrayltetrabenzene (CAS 806-71-3), a certified reference material (molecular formula C28H22, MW 358.47 g/mol) for analytical method development and quality control.
The molecular framework of Buta-1,3-diene-1,2,3,4-tetrayltetrabenzene (C28H22) is characterized by a polycyclic aromatic 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
