Synthesis and application of novel styryl dyes derived from 1,4-diethyl-1,2,3,4-tetrahydro-6-methoxyquinoxaline was written by Satam, Vijay;Rajule, Rajkumar;Bendre, Samir;Bineesh, Purushotthaman;Kanetkar, Vinod. And the article was included in Journal of Heterocyclic Chemistry in 2009.Category: quinoxaline This article mentions the following:
1,4-Diethyl-1,2,3,4-tetrahydro-7-methoxyquinoxaline-6-carboxaldehyde was synthesized, characterized, and condensed with suitably substituted active methylene compounds by classical Knoevenagel condensation to obtain five monostyryl dyes and a bis-styryl dye. These novel styryl dyes have hues varying from orange to violet. The dyes were applied to polyester fibers. The spectral and thermal characteristics of the dyes and fastness properties of the dyed polyester fabric were investigated. In the experiment, the researchers used many compounds, for example, 6-Methoxyquinoxaline (cas: 6639-82-3Category: quinoxaline).
6-Methoxyquinoxaline (cas: 6639-82-3) belongs to quinoxaline derivatives. Quinoxaline derivatives are important constituents of pharmacologically active compounds, including as well as for RNA synthesis inhibition, reactive dyes and pigments, azo dyes, flurox Cylin Dyes, Corrosion Inhibitors and Photovoltaic Polymers. Quinoxaline and its analogues may also be formed by reduction of amino acids substituted 1,5-difluoro-2,4-dinitrobenzene (DFDNB),One study used 2-iodoxybenzoic acid (IBX) as a catalyst in the reaction of benzil with 1,2-diaminobenzene.Category: quinoxaline
