Applications of 87-05-8

Industry Application Process
Personal Care & Cosmetics Fragrance ingredient imparting fresh, grassy, and mildly sweet coumarin notes Used as a fragrance base component, directly incorporated into formulations for perfumes, soaps, and detergents at typical concentrations of 0.1–5% (w/w)
Organic Synthesis Intermediate for fluorescent dyes and fluorescent probes Converted to corresponding derivatives via Vilsmeier-Haack formylation or bromination, for subsequent coupling or labeling reactions
Analytical Chemistry Fluorescent labeling reagent and pH-sensitive probe Undergoes ring-opening/ring-closing tautomerization under alkaline conditions (pH > 9), generating strong blue-green fluorescence (λexem ≈ 365/450 nm), applied in enzyme activity assays and metal ion sensing
Pesticide Development Structural analog for plant growth regulator research Serves as a coumarin-based lead compound in structure-activity relationship (SAR) screening; no commercial agricultural formulations registered to date
