C.I. Basic red 9 is a colorless to red crystalline
solid or green powder.
Pararosaniline Hydrochloride is a red dye used for textiles. Dyes and metabolites, Environmental Testing.
ChEBI: A hydrochloride that is the monohydrochloride of 4,4'-[(4-iminocyclohexa-2,5-dien-1-ylidene)methanediyl]dianiline. One of the major constituents of Basic fuchsin, together with rosanilin, magenta II and new fuchsin.
commonly known as (Para Magenta, Para Rosaniline) (a) 4-(4-Aminobenzyl)benzenamine?and aniline, Aniline hydrochloride, the difficulties and ferric chloride in 170 ℃ heating hours;?(b) aniline,p-Methylaniline and its hydrochloride and iron, ferrous chloride or 1-Nitrobenzene?heating; (C) aniline?and p-Methylaniline?was treated with arsenic oxide; (d) aniline?tetrachloride carbon heat.
Colorless to red crystals or green powder.
ACUTE/CHRONIC HAZARDS: When heated to decomposition Basic Red 9 emits very toxic fumes of hydrogen chloride and nitrogen oxides.
Flash point data for Basic Red 9 are not available; however, Basic Red 9 is probably combustible.
Confirmed carcinogen with experimental carcinogenic and tumorigenic data. Mildly toxic by ingestion. Mutation data reported. When heated to decomposition it emits very toxic fumes of HCl and NOx.
Used as a dye for textiles, paper;
printing, computer and photo imaging inks, leather, and
many consumer products; as a microbiological/microscopy
stain for bacilli, including tubercle and influenza.
Basic red 9 monohydrochloride is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity fromstudies in experimental animals.
UN 3143 Dyes, solid, toxic, n.o.s., or dye intermediates,
solid, toxic, n.o.s., Hazard Class: 6.1; Labels:
6.1—Poisonous materials, Technical Name Required.

May be combustible; powder or liquid
may form explosive mixture with air. Incompatible with
oxidizers (chlorates, nitrates, peroxides, permanganates,
perchlorates, chlorine, bromine, fluorine, etc.); contact may
cause fires or explosions. Keep away from alkaline materials,
strong bases, strong acids, oxoacids, epoxides.
Use a licensed professional
waste disposal service to dispose of this material. Dissolve
or mix the material with a combustible solvent and burn in
a chemical incinerator equipped with an afterburner and
scrubber. All federal, state, and local environmental regulations
must be observed.
