5-Hydroxymethylfurfural (5-HMF) is recognized as a key platform molecule in the bioeconomy, serving as a precursor for the production of biofuels (2,5-dimethylfuran, 5-ethoxymethylfurfuryl ether), biopolymers (2,5-furandicarboxylic acid), and pharmaceutical intermediates. This review systematizes modern approaches to the synthesis of 5-HMF from carbohydrate feedstocks of varying complexity – from monosaccharides (fructose, glucose) to cellulose and lignocellulosic biomass (rice straw). Catalytic systems (homogeneous acids, ionic liquids, heterogeneous catalysts, including functionalized silica gel SiO₂-Imi-SO₃H and sulfated zeolite HSO₃-ZSM-5), solvent effects (dimethyl sulfoxide, biphasic water/organic solvent systems, including dichloromethane/tetrahydrofuran), process intensification methods (ultrasound, microwaves), and strategies for suppressing side reactions are analyzed in detail. The main pathways of 5-HMF chemical transformation are discussed, along with techno-economic and environmental aspects of production based on life cycle assessment (LCA) and bibliometric analysis. Key challenges (catalyst and separation costs, stability) and promising research directions (low-cost bifunctional catalysts, deep eutectic solvents, process integration, electrochemical methods, use of non-food biomass) are identified.
