  • solubility: slightly soluble in water; soluble in ethanol and organic solvents
  • appearance: colorless to pale yellow liquid with a characteristic smoky, sweet odor

usefulness in food, fragrance, and material science

  • contributes to flavor and aroma in smoked meats, cheeses, and barbecue sauces.
  • used in the formulation of natural smoke flavorings and aroma chemicals in perfumery.
  • investigated as a biomarker of wood combustion and forest fires in atmospheric studies.
  • serves as a platform molecule in green chemistry for synthesizing value-added compounds from lignocellulosic biomass.
  • possesses mild antioxidant activity due to its phenolic structure.

antibacterial and antimicrobial activity

  • syringol demonstrates bacteriostatic properties against some gram-positive and gram-negative bacteria.
  • its phenolic ring and methoxy substitutions may disrupt microbial membranes and oxidative pathways.
  • considered a potential natural preservative or synergistic agent in food preservation.
