121-47-1 Usage

Chemical Properties

white powder

Uses

Different sources of media describe the Uses of 121-47-1 differently. You can refer to the following data:
1. 3-Aminobenzenesulfonic acid was used in the synthesis of cytocompatible sulfonated polyanilines. It was used in fabrication of novel glucose biosensor having large active surface area and excellent conductivity.
2. Metanilic acid was used in the synthesis of cytocompatible sulfonated polyanilines. It was used in fabrication of novel glucose biosensor having large active surface area and excellent conductivity. It undergoes microbial desulfonation to 3-aminophenol by Pseudomonas sp. strain S-313. It can be used to produce CN3O6(1-)*Cs(1+) and dicesium salt of N-nitrometanilic acid at temperature of 25°C.

General Description

White powder. Small colorless needles; toxic.

Air & Water Reactions

Water insoluble [Hawley].

Reactivity Profile

Metanilic acid is an amino acid. Reacts weakly with both acids and bases.

Hazard

See aniline.

Fire Hazard

Flash point data for Metanilic acid are not available, however Metanilic acid is probably combustible.

Flammability and Explosibility

Nonflammable

Purification Methods

Crystallise the acid from water (as the hydrate), under CO2 in a semi-darkened room. The solution is photosensitive. Dry it over 90% H2SO4 in a vacuum desiccator. [Beilstein 14 H 688, 14 IV 2640.]

Check Digit Verification of cas no

The CAS Registry Mumber 121-47-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 121-47:
(5*1)+(4*2)+(3*1)+(2*4)+(1*7)=31
31 % 10 = 1
So 121-47-1 is a valid CAS Registry Number.

Acid-resistant catalysis without use of noble metals: Carbon nitride with underlying nickel

Fu, Teng,Wang, Meng,Cai, Weimeng,Cui, Yuming,Gao, Fei,Peng, Luming,Chen, Wei,Ding, Weiping

, p. 2536 - 2543 (2014)

A nanocomposite able to function as a hydrogenation catalyst under strongly acidic conditions without the presence of noble metals is synthesized and thoroughly studied. This specially designed catalyst possesses a unique structure composed of carbon nitride (CN) with underlying nickel, in which the nickel endows the CN with new active sites for hydrogen adsorption and activation while it itself is physically isolated from the reactive environment and protected from poisoning or loss. The CN is inert for hydrogenation without the help of nickel. The catalyst shows good performance for hydrogenation of nitro compounds under strong acidic conditions, including the one-step hydrogenation of nitrobenzene in 1.5 M H2SO4 to produce p-amoniophenol, for which the acid in the reaction system has restricted the catalyst only to noble metals in previous studies. Further characterization has demonstrated that the nickel in the catalyst is in an electron-deficient state because some of its electron has been donated to CN (HRTEM, PES); thus, the hydrogen can be directly adsorbed and activated by the CN (HD exchange, in situ IR and NMR). With this structure, the active nickel is protected by inert CN from the corrosion of acid, and the inert CN is activated by the nickel for catalytic hydrogenation. The assembly of them gives a new catalyst that is effective and stable for hydrogenation even under a strongly acidic environment.

Cu-α-NiMoO4 photocatalyst for degradation of Methylene blue with pathways and antibacterial performance

Ray, Schindra Kumar,Dhakal, Dipesh,Kshetri, Yuwaraj K.,Lee, Soo Wohn

, p. 18 - 32 (2017/08/22)

Cu doped α-NiMoO4 photocatalyst has been synthesized by microwave hydrothermal method. The existence of Cu2+ ions at lattice position of α-NiMoO4 was observed on the basis of XRD, HRTEM, SAED, and EDS analysis. The negative zeta potential values indicate the stability of samples. Solar light driven photocatalytic degradation of Methylene blue (MB) dye in water was used to evaluate the photocatalytic performance of Cu doped α-NiMoO4 photocatalyst. The results revealed that there is an optimum Cu (4 mol%) doping level leads to highly enhanced photocatalytic activity of Cu-α-NiMoO4, as compared to α-NiMoO4 host. The experiment also suggested that active species (OH[rad], O2[rad]? and h+) play a crucial role in the scavenging system. The reduced energy band gap, oxygen vacancy, high BET surface area, and efficient separation of photogenerated electron/hole are responsible for enhancement of photocatalytic performance. MB photodegradation intermediates were identified by high resolution-quadruple time of flight electrospray ionization mass spectrometry (HR-QTOF ESI/MS) in positive ion mode and degradation pathway was proposed. Antibacterial performance was analyzed against Gram-positive (methicillin resistant Staphylococcus aureus and Bacillus Subtilis) and Gram-negative bacteria (Pseudomonas aeruginosa) via well-diffusion method. The formation of larger inhibition zone by small quantity of photocatalyst powder proved the excellent antibacterial performance. The inactivation of microorganism were found in following order: B.Subtilis ? S.aureus ? P.aeruginosa. The result of our study suggested that copper doped α-NiMoO4 photocatalyst is suitable for degradation of organic contaminates as well as effective for growth inhibition of multidrug-resistant microorganisms.
