INTRODUCTION
Lithium bromide (LiBr) is a white, hygroscopic solid. The hygroscopic nature makes it a versatile chemical that can be put to various end uses. It is usually sold in anhydrous form or in aqueous solutions of varying concentrations.
Manufacture
The salt is produced by reaction between lithium carbonate and hydrobromic acid. Alternatively, it is also produced by bromination of lithium hydroxide.

APPLICATIONS
Medicinal Uses
LiBr acts as sedative and is used in treatment of bipolar disorders. It is also a medical humectant.
Air Conditioning
The bromide finds its major application in some air conditioning systems, whereby its 55-60% aqueous solution is used as desiccant (phenomenon of absorption chilling).
Chemical Processes
The salt is further applied in various processes such as:
| Absorption of water vapors (vapor absorption media) |
| Catalyst in dehydrogenation reactions |
| Low temperature heat exchange processes |
| Carbonyl compound condensations with active methylene compounds |
| Some alkylation reactions |
| Inexpensive catalyst in epoxide ring opening using amines |
| Deprotonation and dehydration of organic molecules possessing acidic protons |
| Purification of steroids |
Others
Reconstitution of brines, electrolyte component in Li batteries, and welding flux are some of the feeble uses of LiBr.

Nikethamide is a synthetic organic compound derived from nicotinic acid (vitamin B₃). It consists of a pyridine ring linked to a diethyl amide functional group and belongs to the class of pyridine amide derivatives.
(2-Methoxy-1-methyl-2-oxoethyl)triphenylphosphonium bromide is a stabilized phosphonium salt widely used as an intermediate in organic synthesis. Due to presence of an ester group, the compound generates a stabilized ylide that is particularly useful for synthesizing α, β-unsaturated esters, valuable intermediates in pharmaceuticals, agrochemicals, fragrances, and fine chemicals.
p-tert-Butylphenol (PTBP), is an aromatic organic compound consists of a phenol ring substituted with a tert-butyl group at the para (4-) position, giving it improved thermal stability and hydrophobic properties compared to phenol. PTBP features significant hydrogen bonding capabilities, which enhance its solubility in organic solvents. PTBP is used primarily as an intermediate in the manufacturing of polycarbonate plastics, phenolic resins, and epoxy resins.
Yttrium oxide (Y2O3), also known as yttria, is an air-stable, odorless white powder. It is a highly stable, chemically inert ceramic with a very high melting point. It is insoluble in water but readily dissolves in most strong acids. Increasing the specific surface area and porosity of Y2O3 can further improve its relevant physical and chemical properties.
Ethyl 7,7,7-trifluoro-3-hydroxy-3-methylheptanoate is a fluorinated aliphatic hydroxy ester. The presence of the trifluoromethyl group imparts enhanced metabolic stability, lipophilicity, and unique physicochemical properties compared with non-fluorinated analogues. This compound is primarily used as a synthetic intermediate in pharmaceutical and agrochemical research.
2-Chloro-1,1,1-trimethoxyethane is an organochlorine orthoester compound commonly used as a versatile synthetic intermediate in organic and pharmaceutical chemistry. It is a colorless to pale yellow liquid with good reactivity toward nucleophilic substitution and cyclization reactions, making it valuable in the preparation of heterocyclic and bioactive molecules.
Glycolaldehyde dimer is the cyclic dimeric form of glycolaldehyde, the simplest hydroxyaldehyde. Glycolaldehyde is often supplied as stable dimeric solid, commonly identified as 2,5-dihydroxy-1,4-dioxane.
N,N-Diisopropylethylamine (DIPEA), also known as Hünig’s Base, is a sterically hindered tertiary amine. It is a colorless liquid with a strong amine odor and is widely used as a low nucleophilic organic base in pharmaceutical, agrochemical, and fine chemical synthesis. Due to its bulky structure, DIPEA effectively scavenges acids without participating in unwanted side reactions.
Tris(2,4-di-tert-butylphenyl) phosphite (TDPP) often recognized commercially as Irgafos 168 is a high-performance organophosphorus compound primarily utilized as secondary antioxidant and processing stabilizer. Its characteristic to undergo metallation reaction and provide a cost-effective synthetic processes allows it to be useful in biaryl coupling reactions.
