EU: “Forever Chemicals” in a Conflict of Interests
On 14 July 2026, the European Parliamentary Research Service (EPRS) published a comprehensive briefing on PFAS (per- and polyfluoroalkyl substances), also known as ‘forever chemicals’. The document is intended to serve as a technical basis for MEPs in their upcoming political decisions on PFAS regulation and summarises the current state of scientific knowledge, regulation and procedures.
China Port Congestion
Following a series of typhoon disruptions in East China during the month of August, major ports including Shanghai and Ningbo continue to experience congestion and operational recovery challenges. Industry reports indicate that vessel schedules, yard operations, and equipment circulation remain affected as terminals work through accumulated backlogs from successive storm events.
In focus: Tin(II) sulfide
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.
In focus: Nikethamide BP (N,N-Diethylnicotamide)
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.
In focus: (2-Methoxy-1-methyl-2-oxoethyl)triphenylphosphoniumbromide
(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.
In focus: p-tert-butylphenol (PTBP)
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.
In focus: Yttrium oxide
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.
EU Microplastics Restriction
Under REACH Annex XVII Entry 78, the EU has banned the placing on the market of synthetic polymer microparticles (SPMs) unless a specific derogation applies. Derogations exist for essential uses such as:
In focus:Ethyl 7,7,7-trifluoro-3-hydroxy-3-methylheptanoate
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.
In focus: 2-Chloro-1,1,1- trimethoxyethane
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.
In focus: Glycolaldehyde Dimer
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.
