Other Notes

Same product — same quality — now Sigma-Aldrich brand


Lanthanum(III) nitrate hexahydrate along with aluminium acetylacetonate are dissolved in N,N-dimethylformamide to prepare lanthanum aluminate (LAO) thin films.† It used in the preparation of La0.8Sr0.2Co1-xFexO3 powder, perovskite type lanthanum calcium chromites titanates, LaF3 nanocrystals† and LnFeO3.† Preparation of bis(indolyl) methanes by the reaction of indoles with various aldehydes at room temperature in the presence of a catalytic amount of a La(NO3)3 · 6H2O afforded the corresponding bis(indolyl) methanes.† A wide variety of cyclic and acyclic dithioacetals have been prepared chemoselectively from their corresponding aldehydes with 1,3-dithiol and ethanethiol using catalytic amounts of lanthanum(III) nitrate hexahydrate as a catalyst at room temperature.†
