Bright yellow to yellow-green powder.

Materials in this group are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.

This chemical is sensitive to prolonged exposure to air . Slightly soluble in water.

SYMPTOMS: Symptoms of exposure to this compound include irritation of the gastrointestinal mucosa, nausea and vomiting.

Flash point data are not available for this chemical, but 9-AMINOACRIDINE HYDROCHLORIDE MONOHYDRATE(52417-22-8) is probably combustible.

yellow powder

9-Aminoacridine hydrochloride is a known mutagen and DNA modifier.

Recrystallise it from boiling H2O (charcoal; 1g in 300 mL) to give pale yellow crystals with a neutral reaction. It is one of the most fluorescent substances known. At 1:1000 dilution in H2O it is pale yellow with only a faint fluorescence, but at 1:100,000 dilution it is colourless with an intense blue fluorescence.
