Ibid., Indanthrene S is a coppery coloured paste which is soluble in hot water. 1903Jrnl. Chem. Soc. LXXXIV. i. 446 The substance ‘A’, of the German Patent 135407,..can be purified by dissolving it in concentrated sulphuric acid and allowing the solution to gradually absorb water; well-formed, blue needles separate which, in the case of ‘Indanthrene C’, have the composition C28H10O4N2Br2, and, in the case of indanthrene itself, the composition C28H12O4 N2. 1920[see flavanthrone]. 1920[see indanthrone]. 1921E. de B. Barnett Anthracene & Anthraquinone xvi. 342 The first cyclic azine of the anthraquinone series to be prepared was trans. bisang.-anthraquinonedihydro azine. This was placed on the market under the name Indanthrene Blue, and the name ‘indanthrene’ has come into general use in the literature. The word ‘indanthrene’, however, is a registered trade name (B.A.S.F.) and is applied to many vat dyes which are not azines. Indanthrene Blue is an anthraquinone derivative and ketonic in structure, and in order to denote its ketonic nature the name should terminate in -one. In the following pages, therefore, the word ‘indanthrone’ is used to denote the ketonic hydroazine, indanthrene (without a capital) being used for the parent, oxygen free hydroazine (trans. bisang.-dihydroanthrazine). Where ‘Indanthrene’ is used as a registered trade name it is spelt with a capital. 1922Trade Marks Jrnl. 8 Nov. 2019 Indanthren. 1952K. Venkataraman Chem.
