Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,1'-(p-Tolylmethylene)bis(naphthalen-2-ol) (CAS 60930-61-2) is a high-purity analytical reference standard with the molecular formula C28H22O2 and a molecular weight of 390.47 g/mol.
The molecular framework of 1,1'-(p-Tolylmethylene)bis(naphthalen-2-ol) (C28H22O2) is characterized by a steroid core, a hydroxyl group, an ether linkage. 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), 1,1'-(p-Tolylmethylene)bis(naphthalen-2-ol) 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.
