It has a centrosymmetric angular structure. [2] For many years, the structure was assigned, incorrectly, as having a "linear structure" (EC no. 228-767-9, CAS RN 6358-30-1) which differ in terms of the carbazole ring fusion. [3] Pigment violet 23 is prepared by condensation of an aniline with chloranil. [4]

Different CAS Registry Numbers [1] are used for each form of a substance. For example, something simple like alanine will have one CAS# for the D form, another for L, another for "unspecified" and a fourth one for racemic. There would be another four CAS#s for the hydrochloride, four for the (1:1) sulfate, four for the (2:1)sulfate, etc.
Under the REACH Regulation, it is registered for the manufacture in and/or the import to the European Economic Area in the tonnage band between 10 000 and 100 000 tonnes per year. [2] In e-waste , an average concentration of 340±200 ppm was found in a study conducted in 2011, confirming the widespread occurrence of the chemical in electronic ...
Tetramethylxylylene diisocyanate (TMXDI) is an organic compound with the formula C 6 H 4 (CMe 2 NCO) 2 (Me = CH 3). Introduced in the 1980s by American Cyanamid, the molecule features two isocyanate groups. [1] [2] [3] TMXDI is generally classified as an aliphatic isocyanate, which are generally more UV stable than their aromatic counterparts.
1,1,2,2-tetrachloroethane was used in large amounts to produce other chemicals like trichloroethylene, tetrachloroethylene, and 1,2-dichloroethylene. [ 6 ] Because of its possible carcinogen effects on humans, the production of 1,1,2,2-tetrachloroethane has decreased significantly and is no longer widely used as an end-product. [ 7 ]

1,2,3-Trimethylbenzene 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. It is nearly insoluble in water but soluble in organic solvents. The compound occurs naturally in coal tar and petroleum. It is one of the three isomers of trimethylbenzene.
