INTRODUCTION
Ammonium acetate is a crystalline white solid with a somewhat acetous odour. It is also called the spirit of Mindererus in its aqueous form or Azanium acetate. It is widely used in chemical analysis, in preserving foods, and in pharmaceuticals. It is often used to prepare buffer solutions as it is made up of a weak base and a weak acid combined together.
Manufacture
Ammonium acetate is produced by the neutralization of acetic acid with ammonium carbonate or by saturating glacial acetic acid with ammonia.

Applications
| Ammonium acetate is commonly used as a controlling agent for food acidity. It alters or regulates the alkalinity or acidity of foods. |
| It is also commonly employed in the Knoevenagel condensation technique as a catalyst. The Borch reaction during organic synthesis uses the molecule as one of the greatest sources of ammonia. |
| A protein precipitating reagent is made by combining ammonium acetate with completely distilled water. |
| The substance may also be used as a buffer in ESI (electrospray ionization) mass spectrometry of molecules and proteins, as well as a mobile phase in HPLC (high-performance liquid chromatography). |
| It is used in the production of explosives. |
| It is used for making Foam rubber & Vinyl plastics. |
| In analytical chemistry, the compound is used in the form of a reagent. It is used as a reagent in different dialysis procedures for the elimination of contaminants through diffusion. |
| In agricultural chemistry, ammonium acetate, when used as a reagent, helps in determining soil CEC or cation exchange capacity along with the availability of potassium in the soil. |

Mercuric ammonium chloride, also called white precipitate, is a heavy white odourless amorphous compound used in external treatment of skin diseases and to destroy lice.
Stannic chloride pentahydrate is a tin source compatible with chlorides. Biologically, it induces a slight inhibition in the catalytic activity of the enzyme horse liver alcohol dehydrogenase (HLADH).
Calcium butyrate is an off-white coloured calcium salt and is highly soluble in water. It is stable under normal pressure and temperature. It is used in food supplements and animal feeds. It is also used as a coloring and flavoring agent.
Tridodecylamine is a tertiary fatty amine. Its structure depicts 3 long carbon chains. They are responsible for the hydrophobic nature of the molecule and its hierarchy of applications. It is naturally found in Bos taurus and has a role as rat / mouse metabolite.
Caffeine (anhydrous) is a naturally occurring methylxanthine derivative used as a CNS stimulant, to restore mental alertness and wakefulness in patients experiencing fatigue or drowsiness.
4-Methoxypyridine, a molecule with ether function, is a reactive base. Its nitrogen atom is activated by the methoxy group. It renders the molecule active and thus 4-methoxypyrimidine participates in many chemical processes. Its uses are in intermediates, in synthesis of biologically active moieties, and in proteomic research.
2,6-Lutidine is a liquid product and a semi-volatile compound naturally abundant in tobacco. Its main applications is as reagent in pharmaceuticals and as a solvent in chemical processes.
Dimethylthiocarbamoyl Chloride is an organosulfur compound, a yellow solid. It is often encountered as a yellow syrup. It is a key reagent in the synthesis of arylthiols via the Newman-Kwart rearrangement.
Tetrafluorobenzyl bromide (TFBB), by virtue of presence of 5 fluorine atoms, is a strong electrophile and hence readily combines with nucleophiles. This property results in its extensive usage in derivatization gas chromatography. Commercially, PFBB is applied to make the corresponding alcohol and chloride.
