The LD50 (oral, rats) is 756 mg/kg. Animal studies have shown that 1,2,4-trichlorobenzene affects the liver and kidney, and is possibly a teratogen. [4] There is no regulated occupational exposure limit for chemical exposure, but the National Institute for Occupational Safety and Health recommends no greater exposure than 5 ppm, over an 8-hour workday.
The periodic table is a tabular arrangement of the chemical elements, organized by their atomic number, electron configuration, and chemical properties. It is a useful tool for understanding the patterns and trends of the elements and their interactions. Learn more about the history, structure, and significance of the periodic table on Wikipedia.
Infobox references. 1,2,4-Trimethylbenzene, also known as pseudocumene, is an organic compound with the chemical formula C 6 H 3 (CH 3) 3. Classified as an aromatic hydrocarbon, it is a flammable colorless liquid with a strong odor. It is nearly insoluble in water but soluble in organic solvents. It occurs naturally in coal tar and petroleum ...

Scalar field theory. In theoretical physics, scalar field theory can refer to a relativistically invariant classical or quantum theory of scalar fields. A scalar field is invariant under any Lorentz transformation. [ 1] The only fundamental scalar quantum field that has been observed in nature is the Higgs field.
Two volumes of a catalogue of the remaining works were published by Erich Hermann Mueller von Asow (1892–1964) in 1959. After von Asow's death, Franz Trenner (d. 1993) and Alfons Ott (d. 1976) published the third volume, based on von Asow's notes; this catalogue lists 323 titles, including Strauss's literary writings.
4-Phenyl-1,2,4-triazoline-3,5-dione (PTAD) is an azodicarbonyl compound. PTAD is one of the strongest dienophiles and reacts rapidly with dienes in Diels-Alder reactions. [ 1] The most prominent use of PTAD was the first synthesis of prismane in 1973. [ 2]
The most common use of 1,2-dichloroethane is in the production of vinyl chloride, which is used to make polyvinyl chloride (PVC) pipes, furniture and automobile upholstery, wall coverings, housewares, and automobile parts. [ 4] 1,2-Dichloroethane is also used generally as an intermediate for other organic chemical compounds, and as a solvent.
