Abstract The transition toward renewable resources is pivotal for the sustainability of chemical industry, making exploration biobased furanic platform chemicals derived from plant biomass paramount importance. These compounds, promising alternatives to petroleum‐derived aromatics, face challenges in terms stability under synthetic conditions, limiting their practical application fuel, chemical, and pharmaceutical sectors. Our study presents a comprehensive evaluation furan derivatives various solvents different addressing significant challenge instability. Through systematic experiments involving GC–MS, NMR, FT–IR SEM analyses, we identified key degradation pathways conditions that either promote or lead undesirable products. findings demonstrate strong stabilizing effect polar aprotic solvents, especially DMF, reveal dependence on solvent additive type. This research opens new avenues utilization furans by providing critical insights into behavior significantly impacting development sustainable materials processes. broad appeal this lies its potential guide selection efficient synthesis furan‐based chemicals, marking advance green chemistry science.
