3biphenylyl

3biphenylyl refers to a chemical substituent derived from biphenyl. Biphenyl itself is an organic compound consisting of two phenyl rings connected by a single bond. The biphenylyl group indicates that one of the hydrogen atoms on either of the phenyl rings has been removed to form a point of attachment to another molecule. Specifically, the "3" in 3biphenylyl indicates the position on one of the phenyl rings where the attachment occurs. In the biphenyl molecule, the carbons are numbered starting from the carbon atom directly bonded to the other phenyl ring. Therefore, the 3-position is meta to the point of attachment of the two phenyl rings. This substituent can be found in various chemical compounds, influencing their physical and chemical properties. Its presence can affect solubility, reactivity, and electronic characteristics of the parent molecule.
