(Anthracen-9-ylmethyl)benzylammonium chloride
In the title compound, C(22)H(20)N(+)·Cl(-), the anthracene system makes a dihedral angle of 72.65 (4)° with the benzene ring. The C-N-C-C torsion angles in the chain connecting the benzene ring and anthracene system are 52.24 (15) and -170.73 (11)°. The crystal structure is stabilized by inter-molecular N-H⋯Cl and C-H⋯Cl hydrogen bonds, which link the mol-ecules into tetra-mers about inversion...
متن کاملSkeletal examination by alizarin staining.
A skeletal examination of fetuses is required in regulatory embryo-fetal development studies. This chapter describes a method of skeletal examination using alizarin staining. All fetuses are removed from the mother by caesarean section before birth. The fetuses are first examined externally. For larger species (rabbit and minipig), an internal examination can be performed on the fresh soft tiss...
