Description
501-65-5 Y70JA8HB75 Biphenylacetylene Tolan Acetylene, diphenyl- (8CI) Benzene, 1,1'-(1,2-ethynediyl)bis- Diphenylacetylene AI3-04360 1,2-Diphenylacetylene Diphenylethyne EINECS 207-926-6 Ethyne, diphenyl- NSC 5185 Tolane UNII-Y70JA8HB75 (CAS 501-65-5), molecular formula C14H22 and molecular weight 190.32 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H22, 501-65-5 Y70JA8HB75 Biphenylacetylene Tolan Acetylene, diphenyl- (8CI) Benzene, 1,1'-(1,2-ethynediyl)bis- Diphenylacetylene AI3-04360 1,2-Diphenylacetylene Diphenylethyne EINECS 207-926-6 Ethyne, diphenyl- NSC 5185 Tolane UNII-Y70JA8HB75 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
