Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 208.30 g/mol gives Rel-(1R,2S)-1,2-diphenylcyclobutane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Rel-(1R,2S)-1,2-diphenylcyclobutane (CAS 7694-30-6), molecular formula C16H16 and molecular weight 208.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Rel-(1R,2S)-1,2-diphenylcyclobutane (C16H16) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), Rel-(1R,2S)-1,2-diphenylcyclobutane 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.
