    Key Highlights

    • HIGH PURITY: Supplied at 98.0% minimum assay determined by GC or HPLC, with a defined impurity profile suitable for synthetic work and analytical reference use.
    • SYMMETRIC DIFUNCTIONAL CORE: The two acetyl groups sit at the para positions of a rigid biphenyl scaffold, giving a predictable and selective reaction geometry for condensation and coupling chemistry.
    • TIGHT MELTING RANGE: A controlled melting range of 158-160 C provides a fast, reliable in-house check of batch identity and purity before use.
    • SMALL PACKS AVAILABLE: Offered in 1 g, 5 g and 25 g packs for screening and route development, scaling up to 1 kg for pilot and process work.
    • GOOD SOLVENT COMPATIBILITY: Readily dissolves in ethanol, acetone, chloroform and DMSO, which simplifies formulation of reaction solutions and analytical stock standards.
    • FULL DOCUMENTATION: Each batch is shipped with a Certificate of Analysis covering assay, appearance and melting range.
    • FAST LEAD TIME: Orders are arranged within 7 working days and shipped by courier or by air.

    Product Description

    4,4'-Diacetylbiphenyl is an aromatic diketone in which two acetyl substituents occupy the para positions of a biphenyl backbone. Dideu supplies the material as a white to off-white crystalline powder at 98.0% minimum assay by GC or HPLC, in research quantities from 1 g up to 1 kg. The product is intended for synthetic chemistry, route development and analytical reference applications rather than for bulk industrial consumption.

    The compound combines two useful structural features. The biphenyl unit provides a rigid, planar aromatic spacer, while the two acetyl groups offer equivalent and reactive carbonyl sites that can be transformed by condensation, reduction, halogenation, oxime and hydrazone formation, or transition-metal catalysed coupling. Because the substituents are symmetrically placed at the 4 and 4' positions, reactions at one site are not strongly differentiated from the other, which makes product distribution easier to interpret during development work. The material is practically insoluble in water but dissolves readily in ethanol, acetone, chloroform and DMSO.

    Dideu Group supplies 4,4'-Diacetylbiphenyl with a minimum order quantity of 1 g. Orders are prepared within 7 working days and shipped by courier or by air. Standard documentation includes a Certificate of Analysis and technical data for incoming quality control.

    Potential Applications

    Publicly documented end uses for this compound are limited. The directions listed below are candidate applications inferred from its molecular structure and from the established behaviour of closely related aromatic diketones and biphenyl derivatives. They are not confirmed commercial uses, and buyers should verify suitability for their own process before purchase.

    • May be used as a bifunctional building block in organic synthesis, where the twin acetyl groups serve as anchoring points for constructing more complex substituted biphenyl systems.
    • Is a candidate starting material for pharmaceutical and agrochemical intermediate programmes that require a rigid aromatic ketone precursor amenable to carbonyl transformations.
    • May be evaluated as a monomer for liquid crystalline and rigid-rod polymeric materials, given that the biphenyl core is a well-known mesogenic unit.
    • Is a potential precursor in the development of aromatic ketone photoinitiator systems, since the benzoyl-type chromophore absorbs in the near-ultraviolet region.
    • May be used as a substrate in cross-coupling and condensation reaction studies within academic and contract research laboratories.
    • Is a candidate reference material for chromatographic method development involving aromatic ketone impurity profiling.

    Note on inferred content: All six entries above are structural inferences drawn from the biphenyl backbone and the two acetyl functionalities, together with the known behaviour of analogous aromatic diketones. None of them is a documented industrial application of this specific CAS number.
