Compared with other compounds in its class, the molecular weight of 228.29 g/mol gives 2,2'-Isopropylidenediphenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,2'-Isopropylidenediphenol (CAS 7559-72-0), molecular formula C15H16O2 and molecular weight 228.29 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,2'-Isopropylidenediphenol (C15H16O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, 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.
As a certified reference material (CRM), 2,2'-Isopropylidenediphenol 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.
