Basic Red 9 Chemical Properties,Usage,Production

Chemical Properties

green crystalline powder

Chemical Properties

C.I. Basic red 9 is a colorless to red crystalline solid or green powder.

Uses

Antischistosoma.

Uses

Pararosaniline Hydrochloride is a red dye used for textiles. Dyes and metabolites, Environmental Testing.

Preparation

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.

Definition

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.

General Description

Colorless to red crystals or green powder.

Air & Water Reactions

Insoluble in water.

Health Hazard

ACUTE/CHRONIC HAZARDS: When heated to decomposition Basic Red 9 emits very toxic fumes of hydrogen chloride and nitrogen oxides.

Fire Hazard

Flash point data for Basic Red 9 are not available; however, Basic Red 9 is probably combustible.

Safety Profile

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.

Potential Exposure

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.

Carcinogenicity

Basic red 9 monohydrochloride is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity fromstudies in experimental animals.

Shipping

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.

Properties and Applications

colourful red blue light. Slightly soluble in cold water, soluble in hot water for red, easily soluble in ethanol is cherry red. The strong sulfuric acid for yellow brown, after dilute for purple. Used in the manufacture of blue ink, also can dye tannins mordant dyeing cotton.

Incompatibilities

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.

Waste Disposal

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.
