Chemical Structure

1,2-Bis(4-ethynylphenyl)ethyne CAS 153295-62-6 chemical structure

Description

As a certified reference material (CRM), 1,2-Bis(4-ethynylphenyl)ethyne 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.

1,2-Bis(4-ethynylphenyl)ethyne (CAS 153295-62-6), molecular formula C18H10 and molecular weight 226.27 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C18H10, 1,2-Bis(4-ethynylphenyl)ethyne contains a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 226.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
