General description

1,1,1-Trifluoro-5,5-dimethyl-2,4-hexanedione (TFDMHD) is a 1,3-diketone. It forms Er(3+) complexes. These complexes shows thermally activated slow relaxation of magnetization under a zero direct-current (DC) field.

Application

1,1,1-Trifluoro-5,5-dimethyl-2,4-hexanedione (TFDMHD) may be used in the synthesis of series of NNO ketoimines bearing trifluoromethyl substituents, via Schiff base condensation. It may be used in the synthesis of octahedral Werner-type cobalt(II) complexes. It was used in the preparation of D2-TFDMHD, by mixing with D2O.

Mineralized bone forms when collagen-containing osteoid accrues mineral crystals. This is initiated rapidly (primary mineralization), and continues slowly (secondary mineralization) until bone is remodeled. The interconnected osteocyte network within the bone matrix differentiates from bone-forming osteoblasts; although osteoblast differentiation requires
