4-Methylquinoline

4-Methylquinoline is a heterocyclic aromatic organic compound. Its methyl group is fairly acidic, allowing for condensations to occur at this position, especially when the nitrogen is quaternized. It is used in the preparation of certain dyes.

5-Cholesten-3b-ol

5-Cholesten-3b-ol is an organic chemical substance classified as a waxy steroid of fat. It is an essential structural component of mammalian cell membranes and is required to establish proper membrane permeability and fluidity. In addition, 5-cholesten-3b-ol is an important component for the manufacture of bile acids, steroid hormones, and vitamin D. It is the principal sterol synthesized by animals, predominantly in the liver; however, small quantities can be synthesized in other eukaryotes such as plants and fungi. It is almost completely absent among prokaryotes, i.e. bacteria. Although cholesterol is important and necessary for the aforementioned biological processes, high levels of cholesterol in the blood have been linked to damage to arteries and cardiovascular disease.

ACETYL CHLORIDE

Acetyl chloride undergoes reaction with decalin and aluminum trichloride to afford a tricyclic enol ether.[3] It promotes the cyclopropanation of alkene with dibromomethane or diiodomethane in the presence of Zn dust and copper chloride in ether.[4] Friedel-Crafts reaction of acetyl chloride with benzene in the presence of MCl3 (M = Al or Fe) in the ionic liquid 1-butyl-3-methylimidazolium chloride affords MCl3 adducts of the acetyl chloride, the acetylium ion [CH3CO]+[MCl4]- and the MCl3 adduct of acetophenone.

Aluminum Chloride

Aluminium chloride is the main compound of aluminium and chlorine. It is mainly produced and consumed in the production of aluminium metal, but large amounts are also used in other areas of chemical industry. Aluminium chloride is often cited as a Lewis acid. It is an example of an inorganic compound that "cracks" at mild temperature, reversibly changing from a polymer to a molecule. It finds widespread application in the chemical industry as a catalyst for Friedel–Crafts reactions, both acylations and alkylations. Important products are detergents and ethylbenzene. It also finds use in polymerization and isomerization reactions of hydrocarbons and it can often used as a component of antiperspirant in low doses.

Ammonium Sulphate

Ammonium sulphate is an inorganic salt with a number of commercial uses. The most common use is as a soil fertilizer. It contains 21% nitrogen as ammonium cations, and 24% sulfur as sulfate anions. In fertilizer the purpose of the sulfate is to reduce the soil pH.It is also used as an agricultural spray adjuvant for water soluble insecticides, herbicides, and fungicides.It is also used in the preparation of other ammonium salts.In biochemistry, ammonium sulfate precipitation is a common method for purifying proteins by precipitation.Ammonium sulphate is also a food additive.It has also been used in flame retardant compositions acting much like Diammonium phosphate. As a flame retardant, it lowers the combustion temperature of the material, decreases maximum weight loss rates, and causes an i
