Malononitrile is an organic compound nitrile with the formula CH 2 (CN) 2. It is a colorless or white solid, although aged samples appear yellow or even brown. It is a colorless or white solid, although aged samples appear yellow or even brown.
Like most azobenzenes, Solvent Yellow 7 can be synthesized by the reaction of the phenyldiazonium salt with phenol.The optimal pH value for this azo coupling is 8.5-10. The reaction is carried out in water, since sodium chloride (or potassium chloride) formed in the reaction is soluble in water, while the product precipitates.
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.
Carbonyl cyanide m-chlorophenyl hydrazone (CCCP; also known as [(3-chlorophenyl)hydrazono]malononitrile) is a chemical inhibitor of oxidative phosphorylation. It is a nitrile , hydrazone and protonophore .
m-Phenylenediamine, also called 1,3-diaminobenzene, is an organic compound with the formula C 6 H 4 (NH 2) 2. It is an isomer of o -phenylenediamine and p -phenylenediamine . This aromatic diamine is a colourless solid that appears as needles, but turns red or purple on exposure to air due to formation of oxidation products. [ 3 ]
Sudan III is a dye used for Sudan staining.Similar dyes include Oil Red O, Sudan IV, and Sudan Black B.They are used for staining of triglycerides in frozen sections, and some protein bound lipids and lipoproteins on paraffin sections.
1,5-Diazabicyclo[4.3.0]non-5-ene (DBN) is a chemical compound with the formula C 7 H 12 N 2. [1] It is an amidine base used in organic synthesis. A related compound with related functions is 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU). The relatively complex nature of the formal names for DBU and DBN (hence the common use of acronyms) reflects the ...
It is a phthalate and is the diester of phthalic acid and the 10-carbon branched-chain alcohol 2-propylheptanol. This colorless, viscous liquid is used for softening PVC plastics and is a general purpose PVC plasticizer. [2] It possesses very good plasticizing properties and may be used as a direct replacement for DEHP and DINP in many ...
