02 /Properties

Molecular weight	638.40
Linear formula	Gd(N(Si(CH3)3)2)3
Assay	98%
Form	solid
Application	In many asymmetric catalysis applications, glove box and Schlenk techniques should be employed to prevent exposure of the rare earth catalyst to air and moisture, which can be detrimental to the reaction outcome. Solutions of the catalyst should be made using anhydrous solvents and used shortly after preparation.
Melting point	67-90 °C(lit.)
