Sudan I (also known as CI Solvent Yellow 14 or Solvent Orange R) [1] is an organic compound typically classified as an azo dye. [2] It is an orange-red solid, used to color waxes, oils, petrol, solvents, and polishes. Historically, Sudan I used to serve as a food coloring agent, notably for curry powder and chili powder.
Bismarck brown Y also called C.I. 21000 [1] and C.I. Basic Brown 1, [1] is a diazo dye with the idealized formula [(H 2 N) 2 C 6 H 3 N 2] 2 C 6 H 4. The dye is a mixture of closely related compounds. It was one of the earliest azo dyes, being described in 1863 by German chemist Carl Alexander von Martius. It is used in histology for staining ...
It has the appearance of an orange powder. Aniline Yellow was the first azo dye. it was first produced in 1861 by C. Mene. The second azo dye was Bismarck Brown in 1863. Aniline Yellow was commercialized in 1864 as the first commercial azo dye, a year after aniline black. It is manufactured from aniline.
Sudan II (Solvent Orange 7, C.I. 12140, C 18 H 16 N 2 O) [1] is a lysochrome (fat-soluble dye) azo dye used for staining of triglycerides in frozen sections, and some protein bound lipids and lipoproteins on paraffin sections. It has the appearance of red powder with melting point 156–158 °C and maximum absorption at 493(420) nm.
Oil Blue 35 [1] is a blue anthraquinone dye used for colouring alcoholic and hydrocarbon based solvents, including oils, fats, and waxes. It is used also in lacquers and inks. In some countries, it is used as a fuel dye. It is also used in some blue colored smoke formulations. In microscopy, it is used as a staining dye.
Fuel pumps in Ireland, with green gas oil and red kerosene, and notices that it is an offence to use marked fuels in a motor vehicle.. After August 2002, all European Union countries became obliged to add about 6 mg/L (0.034 oz/bbl) of Solvent Yellow 124, a dye with structure similar to Solvent Yellow 56, to heating fuel.
Methyl yellow, or C.I. 11020, is an organic compound with the formula C 6 H 5 N 2 C 6 H 4 N(CH 3) 2. It is an azo dye derived from dimethylaniline. It is a yellow solid. According to X-ray crystallography, the C 14 N 3 core of the molecule is planar. [3] It is used as a dye for plastics and may be used as a pH indicator.
