Chemical Structure
Description
The occurrence of 7-Phenylbicyclo[2.2.1]hepta-2,5-diene is closely related to an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
7-Phenylbicyclo[2.2.1]hepta-2,5-diene (CAS 40156-12-5), molecular formula C13H12 and molecular weight 168.23 g/mol, is a CATO reference standard with documented purity and traceability.
7-Phenylbicyclo[2.2.1]hepta-2,5-diene (C13H12) contains an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 7-Phenylbicyclo[2.2.1]hepta-2,5-diene 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.
