CI NO 22610 Usage And Synthesis

Description

Direct blue 6 is a benzidine-based dyestuffsomewhat analogous to Direct black 38 (which see). It is adark blue powder. Molecular weight= 932.78; Freezing/Melting point $ 400℃. Hazard Identification (based onNFPA-704 M Rating System): Health 1, Flammability 1,Reactivity 0.

Uses

Direct Blue 6 is a deep blue azo dye used in textiles however contributes to environmental pollution and potentially reproductive toxicity.Environmental toxin on US EPA Toxic Release Inventory list (TRI) list.

General Description

Dark blue microcrystals or black powder.

Air & Water Reactions

Azo dyes can be explosive when suspended in air at certain concentrations. Slightly water soluble.

Reactivity Profile

CI NO 22610 is an azo compound. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides. CI NO 22610 is incompatible with strong oxidizing agents and strong acids .

Health Hazard

ACUTE/CHRONIC HAZARDS: CI NO 22610 is absorbed through the skin. When heated to decomposition it emits very toxic fumes of nitrogen oxides, sodium oxides and sulfur oxides.

Fire Hazard

Flash point data for CI NO 22610 are not available; however, CI NO 22610 is probably combustible.

Safety Profile

Confirmed carcinogen with experimental carcinogenic, neoplastigenic, and tumorigenic data. Experimental teratogenic and reproductive effects. Mutation data reported. When heated to decomposition it emits very toxic fumes of NOx Na2O, and SOx

Potential Exposure

Mutagen; Human Data. Direct Blue 6may be used by artists. It is potentially used to dye fabric,leather, cotton, cellulosic materials, and paper; these arethen used in consumer products (CPSC, EPA). The FDAhas indicated that although Direct Blue 6 has been identified in the literature as a hair dye component, it is not presently used by the cosmetic industry. The primary source forexposure to Direct Blue 6 is at the production site. The initial production step is in a closed system. However, otherproduction operations, such as filter press, drying, andblending, may be performed in the open and, therefore, mayafford a greater potential for worker exposure. The generalpopulation may be exposed to Direct Blue 6 through the useof retail packaged dyes containing this benzidine-based dye.

First aid

If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seekmedical attention immediately. If this chemical contactsthe skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove fromexposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing hasstopped and CPR if heart action has stopped. Transferpromptly to a medical facility. When this chemical hasbeen swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit

storage

Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with directblue 6 you should be trained on its proper handling andstorage. Store in tightly closed containers in a cool, wellventilated area. A regulated, marked area should be established where this chemical is handled, used, or stored incompliance with OSHA Standard 1910.1045.

Shipping

Dyes, solid, toxic, n.o.s. require a label of“POISONOUS/TOXIC MATERIALS.” They fall in HazardClass 6.1.
