305-80-6 Usage

Uses

Different sources of media describe the Uses of 305-80-6 differently. You can refer to the following data:
1. Reagent for determination of phenols, bilirubin, halides and amines. Irreversible probe in membrane protein studies.
2. 4-Diazobenzenesulfonic Acid is a useful catalyst for cellobiose hydrolysis.

Definition

ChEBI: The aromatic diazonium ion that is diazotised 4-aminobenzenesulfonic acid.

Safety Profile

An unstable explosive which mayexplode when touched. Incompatible with metals. Store insmall quantities under refrigeration in loosely pluggedcontainers. Upon decomposition it emits toxic fumes ofNOx and SOx.

Check Digit Verification of cas no

The CAS Registry Mumber 305-80-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,0 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 305-80:
(5*3)+(4*0)+(3*5)+(2*8)+(1*0)=46
46 % 10 = 6
So 305-80-6 is a valid CAS Registry Number.

Ph-SO3H-modified mesoporous carbon as an efficient catalyst for the esterification of oleic acid

Geng, Liang,Yu, Gang,Wang, Yu,Zhu, Yuexiang

, p. 137 - 144 (2012)

Mesoporous carbon materials with thin pore walls (~1.7 nm) were synthesized using low-cost γ-Al2O3 as a hard template and in situ polymerized resorcinol-furfural resin as the carbon precursor. Compared with sugar, resin, a widely used carbon precursor, has higher carbon yield and simplifies the synthetic process. Ph-SO3H modified mesoporous carbon was synthesized by covalent grafting of Ph-SO 3H groups on mesoporous carbon via the diazonium salt. The resulting materials were characterized by means of nitrogen adsorption analysis, TEM, 13C NMR, XRD, FTIR and sulfur elemental analysis. The modified carbons were shown to possess high surface area (~1000 m2/g), a bimodal pore size distribution and high strong acid density (1.86 mmol H +/g). These sulfonated carbons were used as solid acid catalysts in the esterification of oleic acid and methanol, a key reaction in biodiesel production. Compared with the traditional solid acid Amberlyst-15, the optimized carbon catalyst exhibited much higher activity with a rate constant (1.34 h-1) three times to that of Amberlyt-15 and a turnover frequency (TOF) of 128 h-1 eight times that of Amberlyst-15. The efficient catalytic ability was attributed to the high surface area and a proper mesopore texture. This carbon catalyst could then be easily separated from the product by filtration. The catalyst was reused six times, and no distinct activity drop was observed after the initial deactivation.

Electrochemical and impedance spectroscopy studies of various diazonium salts on a glassy carbon electrode

Khoshroo, Maryam,Rostami, Abbas A.

, p. 841 - 846 (2010)

The derivatization of a glassy carbon electrode surface was achieved with and without electrochemical reduction of various diazonium salts in acetonitrile solutions. The surfaces were characterized, before and after their attachment, by cyclic voltammetry and electrochemical impedance spectroscopy to evidence the formation of a coating on the carbon surface. The results were indicative of the presence of substituted phenyl groups on the investigated surface. Also, the effects of diazonium thin films at the surface of a glassy carbon electrode, modification time, and salt concentration on their electrochemical responses in the presence of the Fe(CN)63-/4- probe were investigated. Electrochemical impedance measurements indicated that the kinetics of electron transfer is slowed down when the time and the concentration used to modify the glassy carbon electrode are increased. We therefore modified a glassy carbon surface via its derivatization with and without electrochemical reduction of various diazonium salts in acetonitrile solution. Springer-Verlag 2010.

Synthesis and characterization of eight arylpentazoles

Ek, Stefan,Rehn, Stanley,Wahlstroem, Larisa Yudina,Oestmark, Henric

, p. 261 - 267 (2013/07/05)

p-Nitrophenyl-, p-methoxyphenyl-, p-hydroxyphenyl-, p-t-butylphenyl-, p-HOSO2-phenyl-, 15N-p-N,N-dimethylaminophenyl-, 15N2-p-N,N-dimethylaminophenyl-, and dicyanoimidazopentazole were obtained via different synthetic routes. Cesium, barium, potassium, and sodium salts of the arylpentazoles bearing acidic hydrogens were prepared. NMR spectra (1H, 13C) are reported for the arylpentazoles, their corresponding arylazides, and their salts.
