From plant to fabric: Environmental opportunities associated with annatto dye for sustainable development in the textile industry

Coloration Technology, EarlyView.
Abstract Natural dyes are compounds that occur naturally in several organisms and are classified based on chemical structure and application method. The literature cites several natural dyes used in industrial transformation processes. Annatto dye is used in the food industry, and its biological pigment is extracted from the annatto seed. However, this

Merging Micellar Catalysis and C–H Activation: Silver‐Free Direct Arylation of Fluoroarenes in Water

ChemSusChem, Volume 19, Issue 9, 14 May 2026.
We have developed the first silver‐free protocol for a palladium‐catalyzed direct arylation in water under micellar conditions enabling the coupling of diverse pyridine and fluoroarene derivatives. This method combines the sustainability of aqueous media with the efficiency of C–H activation, obviating the need for organic co‐solvents or stoichiometric

Chronic morpholine exposure of rats

Fundamental and Applied Toxicology, 1989
The chronic toxicity and carcinogenic potential of morpholine were evaluated in 60 Sprague-Dawley rats/sex/group receiving morpholine at mean inhalation exposure concentrations of 0, 10, 50 and 150 ppm for 6 hr/day, 5 days/week, for 104 weeks. Survival, body weight gains, organ weights, hematology, and clinical chemistries were normal in exposed groups

Solvent‐Controlled Electrochemical Cyclization of Areneazo‐2‐(2‐nitro)propanes to Benzo[c]cinnolines

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
Solvent‐mediated redox pathway control enables the first electrochemical cyclization of areneazo‐2‐(2‐nitro)propanes to benzo[c]cinnolines. Mixed solvent systems containing hexafluoroisopropanol (HFIP) and MeOH additives widen the redox potential gaps and stabilize diazonium intermediates via hydrogen bonding, favoring oxidative intramolecular ...

Novel 8-Hydroxyquinoline-Derived V(IV)O, Ni(II), and Fe(III) Complexes: Synthesis, Characterization, and In Vitro Cytotoxicity Against Tumor Cells

Inorganics
We report the synthesis and characterization of five novel metal complexes. Three of them are vanadium complexes with the general formula [VO(Ln)2], where Ln are Schiff bases derived from the condensation of 2-carbaldehyde-8-hydroxyquinoline with either ...
