2-{(E)-[(4-Anilinophenyl)imino]methyl}-4-[(E)-(4-methoxyphenyl)diazenyl]phenol
In the title Schiff base compound, C26H22N4O2, the hydroxy group forms a intramolecular hydrogen bond to the imine N atom and generates an S(6) ring motif. The conformation about the C=N and N=N bonds is E.

Determination of p-Phenylenediamine Antioxidants in Zebrafish Embryos by Gas Chromatography-Tandem Mass Spectrometry with Ultrasonic Extraction [PDF]
p-Phenylenediamine antioxidants (PPDs) are rubber antioxidants that can suppress oxidation, heat, or light radiation to delay the aging of polymer components and extend the service life of rubber products.

Adverse reactions to permanent hair dyes are frequent, and primarily result from sensitization to p-phenylenediamine (PPD).To investigate the degree of cross-reactivity to a chemically similar dye, hydroxyethyl-p-phenylenediamine sulfate (HPPS), and whether this might be a dyeing alternative for patients who are sensitive to PPD.HPPS was patch tested ...

An analytical study on the reduction of neotetrazolium chloride by the terminal electron transport system [PDF]
In order to determine the steps with which the reaction of neotetrazolium chloride reduction conjugates in the terminal electron transport system, an analytical study on the neotetrazolium reduction by tissue homogenates was carried out using various ...

Interspecific somatic hybrids between Solanum bulbocastanum and S. tuberosum and their haploidization for potato breeding. [PDF]
Protoplast fusion between incongruent Solanum bulbocastanum and S. tuberosum haploids was accomplished to produce hybrids combining elite traits from both parents. We identified 11 somatic hybrids out of 42 regenerants analyzed through ISSR markers. Some

Paraphenylenediamine Poisoning in Tunisia: A Case Report
Paraphenylenediamine (PPD) represents the main active substance in the color of hair dyes. In Tunisia, PPD poisoning is very common, especially in rural areas where the consequences linked to this toxic substance are still unknown.
