Biphenyl is a solid at room temperature, with a melting point of 69.2 °C (156.6 °F). In the gas phase the molecule exists in two enantiomorphic twisted forms with an angle between the planes of the two rings of 44.4(2)°. [6] In the room-temperature solid, biphenyl is crystalline with space group P2 1 /c, which does not allow for chiral ...
4-(4-Methylphenyl)-4-oxobutanoic acid is an organic carboxylic acid. The preparation of it is used for undergraduate teaching of organic chemistry synthesis.
4-Cyano-4'-pentylbiphenyl is a commonly used nematic liquid crystal with the chemical formula C 18 H 19 N. It frequently goes by the common name 5CB. 5CB was first synthesized by George William Gray , Ken Harrison, and J.A. Nash at the University of Hull in 1972 and at the time it was the first member of the cyanobiphenyls.
The industrial synthesis of 4,4′-biphenol was developed by Allan Hay in the 1960s. [2] [3] As the direct oxidative coupling of phenol gives a mixture of isomers, [4] [5] 4,4′-biphenol is instead prepared from 2,6-di-tert-butylphenol, where para-coupling is the only possibility. [3]
4,4'-Dihydroxybiphenyl: ... Dihydroxybiphenyls are synthesized through various organic reactions and are used in the preparation of polyether liquid crystals. [1]
4,4′-Bis(dimethylamino)benzhydrol is an organic compound with the formula (Me 2 NC 6 H 4) 2 CH(OH), where Me is methyl. It is a white solid that is soluble is a variety of organic solvents. The compound is notable as the reduced derivative of Michler's ketone. It is a precursor to triarylmethane dyes. [1]
4-Methylphenethylamine (4MPEA), also known as para-methylphenethylamine, is an organic compound with the chemical formula of C 9 H 13 N.4MPEA is a human trace amine associated receptor 1 (TAAR1) agonist, [2] a property which it shares with its monomethylated phenethylamine isomers, such as amphetamine (α-methylphenethylamine), β-methylphenethylamine, and N-methylphenethylamine (a trace amine).
4-Aminobiphenyl (4-ABP) is an organic compound with the formula C 6 H 5 C 6 H 4 NH 2. It is an amine derivative of biphenyl . It is a colorless solid, although aged samples can appear colored. 4-Aminobiphenyl was commonly used in the past as a rubber antioxidant and an intermediate for dyes. [ 5 ]
