Articles of 9-(2-phenylethenyl)anthracene … For example, 2-chloroanthracene has a melting point 6 K higher than anthracene, whereas the melting point of 1-chloroanthracene is over 100 K lower than anthracene [14]. Similarly, although the substituent group is the same for 2-and 9-anthracenecarboxylic acid, the melting point of 2-anthracenecarboyxlic acid is significantly higher, over 60 K higher, than its 9-carbon position counterpart. Chemsrc provides Benz(a)anthracene(CAS#:56-55-3) MSDS, density, melting point, boiling point, structure, formula, molecular weight etc. Articles of Benz(a)anthracene are included as well.
