Applications
Dithranol was used as a matrix in MALDI TOF mass spectrometry measurements of sol-gel films for DNA microarray applications. It was also used as matrix in matrix-assisted laser desorption/ionization-mass spectrometry (MALDI-MS) and liquid secondary ion-tandem mass spectrometry (LSI-MS/MS) for the analysis of synthetic polymers to generate values for the average mass and the mass of the end groups. It was also used in MALDI-MS for direct detection of condensed tannins in bark. It is successfully used for the treatment of psoriasis.

Solubility
Insoluble in water. Soluble in acetic acid, chloroform (20 mg/mL), acetone, benzene, solutions of alkali hydroxides, fixed oil. Slightly soluble in 95% ethanol, alcohol, ether, and glacial acetic acid.

Notes
Store in cool, dry place in a well sealed container. Store away from oxidizing agents.
