Most of the nitrobenzene produced in the United States is used to manufacture a chemical called aniline.  Nitrobenzene is also used to produce lubricating oils such as those used in motors and machinery.

Nitro-group is meta-directing. The nitro group strongly deactivates the benzene ring towards electrophilic substitution. Nitro group is electron withdrawing group and thus causes electron deficiency at ortho and para positrons as is clear from the resonating structures of nitro benzene.

In order to see the spots on the chromatogram, you will apply a solution of ninhydrin to the paper.

 Ninhydrin will react with the amino acid to produce a purple compound. Silica gel will serve as the stationary phase in the thin layer chromatography procedures.

TCL is based on the principle of separation through adsorption type. The separation relies on the relative empathy of compounds towards the mobile phase and stationary phase.

Perchloric acid is a mineral acid with the formula HClO4. Usually found as an aqueous solution, this colorless compound is a stronger acid than sulfuric acid, nitric acid and hydrochloric acid. It is a powerful oxidizer when hot, but aqueous solutions up to approximately 70% by weight at room temperature are generally safe, only showing strong acid features and no oxidizing properties.

L-methionine is the L-enantiomer of methionine. It has a role as a nutraceutical, a micronutrient, an antidote to paracetamol poisoning, a human metabolite and a mouse metabolite. It is an aspartate family amino acid, a proteinogenic amino acid, a methionine and a L-alpha-amino acid.

Trifluoroacetic acid is an organofluorine compound with the chemical formula CF₃CO₂H. It is a structural analogue of acetic acid with all three of the acetyl group's hydrogen atoms replaced by fluorine atoms and is a colorless liquid with a vinegar-like odor.

Magnesium fluoride is an inorganic compound with the formula MgF2. The compound is a white crystalline salt and is transparent over a wide range of wavelengths, with commercial uses in optics that are also used in space telescopes. It occurs naturally as the rare mineral sellaite.

The main application of magnesium fluoride is in optics, due to its distinctive transparency over a wide range of wavelengths. It is evaporated under vacuum to form anti-reflective layers.

Manganese(III) acetate describes a family of materials with the approximate formula Mn(O2CCH3)3. These materials are brown solids that are soluble in acetic acid and water. They are used in organic synthesis as oxidizing agents.

Manganese(II) Acetate Tetrahydrate is a moderately water soluble crystalline Manganese source that decomposes to Manganese oxide on heating.

MERCURIC CHLORIDE AR Used in photography, disinfectants, wood preservatives, fungicides. Mercury chloride (HgCl2) is a highly toxic compound that volatizes slightly at ordinary temperature and appreciably at 100 degrees C. It is corrosive to mucous membranes and used as a topical antiseptic and disinfectant.

Mercuric Oxide Yellow AR is functional as a chemical intermediate for chlorine monoxide; 

antiseptic in pharmaceuticals, mercury salts, organic mercury compounds etc.

Mercuric Oxide is a yellow to orange-yellow, odorless, crystalline powder. It is used in alkaline batteries and pigments, as a seed protectant, and as a preservative in cosmetics.
