INTRODUCTION
Iodine is anon-metallic, dark-grey/purple-black, lustrous, solid element. It is the heaviest and the rarest of stable halogens that can be found on the crust of earth.About fifty percent of all iodine produced and manufactured worldwide is used to form Organoiodine compounds. Iodine is an important element for many health-sustaining processes and essential for human thyroid health.
Manufacture
Iodine is obtained from: a) Brine which contains iodide ions (in particular, brines that are adjacent to oil and natural gas fields) OR b) Nitrate ores.
Industrial process of further purification includes : i) the blowing out method OR ii) the ion-exchange method

(S)-Oxetan-2-yl-methanamine is a chiral oxetane-containing primary amine. The compound features a strained four-membered oxetane ring and an aminomethyl substituent, making it a valuable building block in modern medicinal chemistry. Due to its unique physicochemical properties, including increased polarity and metabolic stability compared with conventional alkyl groups, it is widely employed as an advanced pharmaceutical intermediate in drug discovery and development programs.
Guanidine carbonate is a white, crystalline, water-soluble compound with an alkaline and ionic nature. Composed of guanidinium cations and carbonate anions, it offers chemical stability, buffering capacity, and good formulation compatibility. In textile applications, it is used in formulations and fabric treatments for its thickening, softening, lubricating, anti-static, and flame-retardant properties, contributing to improved fabric finish and performance.
Tin(II) sulfide (SnS) has emerged as a safe and sustainable semiconductor owing to its non-toxicity, low cost, and natural abundance. It has attracted significant interest for solar energy conversion in thin-film photovoltaic devices because of its suitable band gap, which is approximately 1.3 eV in the orthorhombic phase and 1.5-1.7 eV in the cubic phase. In addition to photovoltaic applications, SnS is used in solid-state lubricants, near-infrared detectors, Lithium-ion batteries, and various sensing devices.
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.
