INTRODUCTION
Polyethylene glycols (PEG), also known as macrogols, are liquid or solid polymers of the general formula H(OCH2CH2)n OH, where n is greater or equal to four.
MANUFACTURE
PEG’s are produced by the interaction of ethylene oxide with water, ethylene glycol or ethylene glycol oligomers. The reaction is catalyzed by acidic or basic catalysts

(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.
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.
