Hamidian, H. published the artcileSynthesis of new 1,3,4-thiadiazole derivatives containing of morpholine ring, Quality Control of 116-63-2, the publication is Asian Journal of Chemistry (2013), 25(1), 487-489, database is CAplus.
The synthesis of new of 1,3,4-thiadiazole derivatives containing of morpholine ring were investigated. In this study, the derivatives of naphthol, amine and phenol were reacted with morpholine-4-carbonyl chloride. Then, prepared solutions were added to diazotized 2-amino-5-mercapto-1,3,4-thiadiazole to give 2-amino-5-mercapto-1,3,4-thiadiazole products. These dyes were characterized by elemental anal. and spectral analyses (IR, 1H NMR, 13C NMR and mass spectra).
Asian Journal of Chemistry published new progress about 116-63-2. 116-63-2 belongs to naphthyridine, auxiliary class Sulfonic acid,Amine,Naphthalene,Alcohol,Organic Pigment, name is 4-Amino-3-hydroxynaphthalene-1-sulfonic acid, and the molecular formula is C10H9NO4S, Quality Control of 116-63-2.
