CATO supplies 29079-00-3 4-Ethynylbiphenyl Biphenyl, 4-ethynyl- 4-Ethynyl-1,1'-biphenyl 4-05-00-02280 (Beilstein Handbook Reference) 1,1'-Biphenyl, 4-ethynyl p-Biphenylacetylene 4-Biphenylacetylene 4-Biphenylylacetylene BRN 1927901 LY 81979 (CAS 29079-00-3), a certified reference material (molecular formula C14H22, MW 190.32 g/mol) for analytical method development and quality control.

Based on its molecular formula C14H22, 29079-00-3 4-Ethynylbiphenyl Biphenyl, 4-ethynyl- 4-Ethynyl-1,1'-biphenyl 4-05-00-02280 (Beilstein Handbook Reference) 1,1'-Biphenyl, 4-ethynyl p-Biphenylacetylene 4-Biphenylacetylene 4-Biphenylylacetylene BRN 1927901 LY 81979 contains an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 190.32 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.
