  2. Pigment violet 23 - Wikipedia

    en.wikipedia.org/wiki/Pigment_violet_23

    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]

    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 ...

    en.wikipedia.org/wiki/Alazocine

    Alazocine shows stereoselectivity in its pharmacodynamics. [6] The (−)-enantiomer is a non-selective and high-affinity ligand of the μ-, κ-, and δ-opioid receptors (K i = 3.0, 4.7, and 15 nM in guinea pig brain membranes) with very low affinity for the sigma σ 1 receptor (K i = 1,800–4,657 nM in guinea pig brain membranes).

    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.

    1-Chloro-3,3,3-trifluoropropene (HFO-1233zd) is the unsaturated chlorofluorocarbon with the formula HClC=C(H)CF 3. The compound exists as E- ( cis- ) and Z- ( trans- ) isomers. The trans- isomer of this colorless gas is of interest as a more environmentally friendly (lower GWP; global warming potential) refrigerant in air conditioners. [ 1 ]

    en.wikipedia.org/wiki/1,1,2,2-Tetrachloroethane

    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 ]
