Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 202.25 g/mol gives 1-Ethynyl-4-(phenylethynyl)benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Ethynyl-4-(phenylethynyl)benzene (CAS 92866-00-7) is a high-purity analytical reference standard with the molecular formula C16H10 and a molecular weight of 202.25 g/mol.
1-Ethynyl-4-(phenylethynyl)benzene (C16H10) 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.
As a certified reference material (CRM), 1-Ethynyl-4-(phenylethynyl)benzene 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.
