p-Phenylenediamine (PPD) is an organic compound with the formula C 6 H 4 (NH 2) 2. This derivative of aniline is a white solid, but samples can darken due to air oxidation. [1] It is mainly used as a component of engineering polymers and composites like kevlar. It is also an ingredient in hair dyes and is occasionally used as a substitute for ...
m-Phenylenediamine, also called 1,3-diaminobenzene, is an organic compound with the formula C 6 H 4 (NH 2) 2. It is an isomer of o -phenylenediamine and p -phenylenediamine . This aromatic diamine is a colourless solid that appears as needles, but turns red or purple on exposure to air due to formation of oxidation products. [ 3 ]
Synthesis of benzotriazole involves the reaction of o-phenylenediamine, sodium nitrite, and acetic acid. The conversion proceeds via diazotization of one of the amine groups: [7] [8] The synthesis can be improved when the reaction is carried out at low temperatures (5–10 °C) and briefly sonicated in an ultrasonic bath.

6PPD is an organic chemical widely used as stabilising additive (or antidegradant) in rubbers, such as NR, SBR and BR; all of which are common in vehicle tires. [1] Although it is an effective antioxidant it is primarily used because of its excellent antiozonant performance.

As interest in taking glucagon-like peptide-1 receptor agonist (GLP-1 agonist) medications, such as Zepbound and Wegovy, for weight loss, research continues to examine potential new side effects ...
It acts primarily as a stool lubricant, and is thus not associated with abdominal cramps, diarrhea, flatulence, disturbances in electrolytes, or tolerance over long periods of usage, side effects that osmotic and stimulant laxatives often engender (however, some literature suggests that these may still occur).
