Usage

Uses

p-Quinonimine (Acetaminophen Impurity 7 (4-quinoneimine)) is an impurity of Acetaminophen (A161220), an analgesic and antipyretic drug. Acetaminophen is a pain reliever commonly used to treat headache, muscle aches, arthritis, and other acute or chronic painful conditions.

Safety Profile

Experimental reproductiveeffects. The solid decomposes violently (nearlyexplosive).When heated to decomposition it emits toxicfumes of NOx.

3D multiporous Co,N co-doped MoO2/MoC nanorods hybrids as improved electrode materials for highly sensitive simultaneous determination of acetaminophen and 4-aminophenol

3D multiporous Co, N co-doped MoO2/MoC (3D Co,N-MoO2/MoC) nanorods hybrids were successfully synthesized via carburizing core-shell ZIF-67-cladded MoO3 nanorods precursor at high temperature. As-fabricated Co,N-MoO2/MoC nanorods coated glassy carbon electrodes (GCE) was demonstrated to possess superior electrocatalytic activity for the electro-oxidation of acetaminophen (AC) and 4-aminophenol (4-AP). Such excellent electrochemical performance was largely attributed to the synergistic effect of the unique multiporous structure, the optimal component and abundant active sites of the nanorods. The corresponding electrode reaction mechanisms were studied in detail in this article. Under optimal conditions, the linear detection ranges were 0.05–200.0 μmol/L for AC and 0.05–140.0 μmol/L for 4-AP, respectively, with the low detection limits of 0.013 μmol/L and 0.012 μmol/L. Furthermore, the 3D Co,N-MoO2/MoC/GCE revealed excellent sensitivity, good reproducibility, stability and anti-interference ability. The developed electrode was evaluated towards the detecting AC and 4-AP in biological fluids, environment water and pharmaceutical formulations with satisfactory recovery, which had a broad application prospect.

P-Aminophenol sensor based on tetra-β-[3-(dimethylamine)phenoxy] phthalocyanine cobalt(ii)/multiwalled carbon nanotube hybrid

A highly efficient catalyst is a key challenge for developing electrochemical sensors for p-aminophenol (4-AP), which widely exists in the environment. In this paper, we describe a feasible synthesis for a tetra-β-[3-(dimethylamine)phenoxy] phthalocyanine

Electrochemical Detection of Escherichia coli from Aqueous Samples Using Engineered Phages

In this study, an enzyme-based electrochemical method was developed for the detection of Escherichia coli (E. coli) using the T7 bacteriophages engineered with lacZ operon encoding for beta-galactosidase (β-gal). The T7lacZ phages can infect E. coli, and have the ability to trigger the overexpression of β-gal during the infection of E. coli. The use of the engineered phages resulted in a more sensitive detection of E. coli by (1) overexpression of β-gal in E. coli during the specific infection and (2) release of the endogenous intracellular β-gal from E. coli following infection. The endogenous and phage-induced β-gal was detected using the electrochemical method with 4-aminophenyl-β-galactopyranoside (PAPG) as a substrate. The β-gal catalyzed PAPG to an electroactive species p-aminophenol (PAP) which could be monitored on an electrode. The electrochemical signal was proportional to the concentration of E. coli in the original sample. We demonstrated the application of our strategy in aqueous samples (drinking water, apple juice, and skim milk). Using this method, we were able to detect E. coli at the concentration of approximately 105 CFU/mL in these aqueous samples in 3 h and 102 CFU/mL after 7 h. This strategy has the potential to be extended to detect different bacteria using specific bacteriophages engineered with gene encoding for appropriate enzymes.
