sym-Diphenylacetylene, min. 95 %, 25 g

sym-Diphenylacetylene is an organic diarylacetylene reagent supplied at a minimum purity of 95 %, with CAS number 501-65-5 and empirical formula C₁₄H₁₀. Its molar mass is 178,23 g/mol. Physical data include a boiling point of 300 °C and a flash point of 126 °C, supporting controlled handling in synthetic and analytical laboratory settings. This material is The symmetrical diphenyl structure is commonly used in organic synthesis, coupling chemistry, and method development where a stable acetylene derivative is needed. Available from manufacturer Carl ROTH, the grade matches the stated identity and purity for routine laboratory use. Researchers working with acetylene intermediates, model compounds, or preparative organic chemistry can integrate this pack size into screening, scale-up trials, and reference work without additional reformulation steps. Standard laboratory precautions for organic solids apply during weighing, dissolution, and storage of the solid material.
