119-34-6 Usage

Chemical Properties

Different sources of media describe the Chemical Properties of 119-34-6 differently. You can refer to the following data:
1. DARK BROWN FINE CRYSTALLINE POWDER
2. 4-Amino-2-nitrophenol is a dark red crystalline or reddish-purple solid.

Uses

Different sources of media describe the Uses of 119-34-6 differently. You can refer to the following data:
1. 4-Amino-2-nitrophenol has been used in dyeing human hair and animal fur. The typical concentration in the “semipermanent” hair dyes was estimated to be on the order of 0.1–1.0%.
2. 4-Amino-2-nitrophenol was used in determination of aminonitrophenols in hair dyes by differential pulse voltammetry and HPLC with electrochemical detection. It is commonly used as semipermanent (nonoxidative) hair colorant and toner in permanent (oxidative) hair dye products.

General Description

Dark red plates, needles or reddish-purple powder. Melting point 125-127°C.

Air & Water Reactions

Sensitive to oxidation upon prolonged exposure to air. Insoluble in water.

Reactivity Profile

4-Amino-2-nitrophenol may react with strong oxidizing agents, strong bases, acid chlorides and acid anhydrides .

Fire Hazard

Flash point data for 4-Amino-2-nitrophenol are not available. 4-Amino-2-nitrophenol is probably combustible.

Safety Profile

Suspected carcinogen with experimental carcinogenic data. Very poisonous by intraperitoneal route. Moderately toxic by ingestion. A severe eye heated to decomposition it emits toxic fumes of NOx.

Potential Exposure

In dye formulation for furs and hair

Carcinogenicity

Under the conditions of the bioassay, the compound was carcinogenic in male rats inducing transitional cell carcinomas of the urinary bladder (controls 0/15, lowdose 0/46, high dose 11/39). The same tumor was also observed in three dosed female rats and may have been associated with the administration of the chemical. No evidence of carcinogenic activity was found in the mice.

Shipping

UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. UN3143 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

Incompatibilities

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. It is unknown if this nitro compound is explosive; some are flammable and explosive, and the contact with alkali increases thermal sensitivity of these materials.

Check Digit Verification of cas no

The CAS Registry Mumber 119-34-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 119-34:
(5*1)+(4*1)+(3*9)+(2*3)+(1*4)=46
46 % 10 = 6
So 119-34-6 is a valid CAS Registry Number.

Magnetically Recoverable Gold Nanorods as a Novel Catalyst for the Facile Reduction of Nitroarenes Under Aqueous Conditions

Lamei, Kamran,Eshghi, Hossein,Bakavoli, Mehdi,Rostamnia, Sadegh

, p. 491 - 501 (2017)

Abstract: In this work, cysteine-functionalized Fe3O4@Carbon magnetic nanoparticles were used for the synthesis of gold nanorods. Fe3O4@C nanoparticles were first prepared by synthesis of Fe3O4magnetic nanoparticles (MNPs), and then carbon-coated MNPs (Fe3O4@C) were synthesized by glucose carbonization using a hydrothermal method. Finally, the gold NRs were loaded on the modified surface of Fe3O4@C MNPs. The designed magnetically recoverable gold nanorods, after full characterization by FTIR, SEM, TEM, TGA, VSM, XRD, and ICP-OES, were applied to the reduction of nitroarenes. The Fe3O4@C@Cys–Au nanorods showed higher performance than Fe3O4@C@Cys–Au nanospheres in a selective facile reduction of nitroarenes to the corresponding aminoarenes in aqueous medium at room temperature using NaBH4.

Vanadium pentoxide as a catalyst for regioselective nitration of organic compounds under conventional and nonconventional conditions

Venkatesham,Reddy, K. Rajendar,Rajanna,Veerasomaiah

, p. 921 - 926 (2014/04/03)

Vanadium pentoxide is used as an efficient catalyst for regioselective nitration of aromatic compounds under conventional and nonconventional conditions such as ultrasonically assisted (USAR) and microwave-assisted reactions (MWAR). The reactions underwent smoothly and afforded good yields of products with high regioselectivity. Observed longer reaction times (about 8 h) in V2O5 catalyzed reactions reduced to (0.5/30 min) under sonication and (90 s) in the case of MWAR. When ortho position is blocked, para derivatives are obtained as end products while ortho nitro products are obtained when para position is blocked.
