used to make phosphate esters such as tricresyl phosphate: Potassium dichromate: a common inorganic chemical reagent, most commonly used as an oxidizing agent in various laboratory and industrial applications Potassium hydroxide: a strong base; precursor to most soft and liquid soaps as well as numerous potassium-containing chemicals
2-Tolidine (orthotolidine, o-tolidine; not to be confused with o-toluidine) is an organic compound with the chemical formula (C 6 H 4 (CH 3)NH 2) 2. Several isomers are known; the 3-tolidine derivative is also important commercially. It is a colorless compound although commercial samples are often colored. It is slightly soluble in water.
Common reaction conditions include use of sodium or potassium alkoxide as base in hexane or tetrahydrofuran solvents, at temperatures ranging between 200–400 °C. A hydrolysis step is also required in the synthesis. The Madelung synthesis is important because it is one of few known reactions that produce indoles from a base-catalyzed thermal ...
Color Developing Agent 2 is the second in the series of color developing agents used in developing color films.It is commonly known as CD-2 and is chemically known as 4-diethylamino-o-toluidine, 1,4-benzenediamine, N4,N4-diethyl-2-methyl-, N1,N1-diethyl-3-methylbenzene-1,4-diamine, or 4-(diethylamino)-2-methylaniline.

This reagent is inexpensively available for laboratory use. It is a by-product from the production of ortho-toluenesulfonyl chloride (a precursor for the synthesis of the common food additive and catalyst saccharin), via the chlorosulfonation of toluene: [5] CH 3 C 6 H 5 + SO 2 Cl 2 → CH 3 C 6 H 4 SO 2 Cl + HCl
The smear is first treated with chloroform to remove fats . Smear applied with Alberts stain which contains cationic dyes such as toluidine blue and malachite green. Toluidine blue preferentially stains granules while malachite green stains cytoplasm. The granules show the typical monochromatism nature, this is used to demonstrate granules
