Chemical Structure
Description
1,2,3,4,5-Pentaphenyl-1,3-cyclopentadiene (CAS 2519-10-0), molecular formula C35H26 and molecular weight 446.58 g/mol, is a CATO reference standard with documented purity and traceability.
1,2,3,4,5-Pentaphenyl-1,3-cyclopentadiene (C35H26) contains a polycyclic aromatic 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.
CATO manufactures 1,2,3,4,5-Pentaphenyl-1,3-cyclopentadiene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
