What is 1,3-Indanedione?
Chemical properties
YELLOW TO GREEN FINE CRYSTALLINE POWDER
The Uses of 1,3-Indanedione
It is used in the first stage of forensic identification of latent fingerprints. It is particularly useful for paper, and for items printed with thermal inks such as receipts.
Definition
ChEBI: A member of the class of indanones that is indane in which the hydrogens at positions 2 and 4 have been replaced by oxo groups.
Purification Methods
Recrystallise it from EtOH or *C6H6. In dilute alkali it gives a deep yellow solution of the enol. [Bernasconi & Paschalis J Am Chem Soc 108 2969 1986]. [Beilstein 7 IV 2344.]
