Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (2-Methylpropane-1,1-diyl)dibenzene (CAS 1634-11-3), a certified reference material (molecular formula C16H18, MW 210.31 g/mol) for analytical method development and quality control.
The molecular framework of (2-Methylpropane-1,1-diyl)dibenzene (C16H18) 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).
As a certified reference material (CRM), (2-Methylpropane-1,1-diyl)dibenzene 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.
