INTRODUCTION
A colorless crystalline solid. Much denser than water and insoluble in water but soluble in chloroform and ethanol. Toxic by ingestion. Vapors are narcotic in high concentration. It is commonly employed as an electron acceptor in organic synthesis reactions. Carbon tetrabromide is also an efficient catalyst for regioselective ring opening of epoxides with alcohols.
Manufacture
It is made via bromination of methane using HBr or Br2. It can be also prepared by more economical reaction of tetrachloromethane with aluminium bromide at 100 °C.

Methyl magnesium chloride is the simplest of Grignard’s reagents. The neat molecule is sensitive to air and moisture. Therefore, it is offered as solution in THF with variable molarity values.
Polysorbate 20 is a gentle, oily, liquid cosmetic additive that functions as a non-ionic surfactant and wetting agent that enhances the spread-ability of liquids.
Iodomethane, also known as methyl iodide, is a colorless, non-flammable liquid with pungent, ethereal odor that darkens on exposure to light. It occurs naturally in oceans as a product of marine algae.
1,4-Dibromobutane is a chemical compound from the group of aliphatic, saturated halogenated hydrocarbons. 1,4-Dibromobutane shows similar reactions as the mono-brominated 1-bromobutane, however, in contrast, it is doubly functionalized.
Tetrabutylammonium fluoride trihydrate (TBAF trihydrate) is a hygroscopic solid and is a versatile reagent in many chemical reactions. It us usually consumed in aldol-type condensation, Michael-type, and ring opening reactions.
Pyrophosphoryl chloride is colourless to pale yellow liquid, reasonably easy to handle. It reacts violently with water & miscible with most organic solvents.
It is used in pharmaceutical and other organic synthesis, as laser materials and electronic components.
Benzilic acid ethyl ester is an oil organic liquid. Its reactivity is attributed to the presence of the hydroxyl group at alpha-position to the carboxylic acid group and hence it participates in various reactions leading to value-added intermediates and APIs.
Bromobenzene, an aryl halide, is a clear, colorless liquid with a pleasant odor. It is soluble in methanol and diethyl ether, and very slightly soluble in cold water.
