Synthetic Communications, 25, p. 4081, 1995 DOI: 10.1080/00397919508011485
Synthesis, p. 998, 1987 DOI: 10.1055/s-1987-28146
[Purification Methods]

Dry the aldehyde over Na2SO4 and fractionate it in a vacuum. The 2,4-dinitrophenylhydrazone forms red crystals from MeOH with m 238-240o, and the semicarbazone has m 210-212o (from MeOH). [Erne et al. Helv Chim Acta 34 148 1951, Beilstein 27 III/IV 2615.]
