Description

A liquid with a sharp, fragrant odor; [HSDB] Colorless liquid with a fruity odor; Stabilized with 10-20 ppm MEHQ; [OECD SIDS]

Sources/Uses

Used as a monomer in the production of acrylic resins; [HSDB] Used in organic synthesis, as latent solvent in paints and lacquers, as substitute for n-butyl alcohol, in paint removers, for fluorometric determinations, liquid chromatography, and in fruit flavor concentrates; [NTP] Used as comonomer for polymers used in surface coatings, films and pressure sensitive adhesives, dispersions, and construction materials; [OECD SIDS]

Comments

A skin sensitizer; [Quick CPC] May polymerize exothermically on exposure to heat or if contaminated; [CAMEO] High vapor concentrations can cause mild and temporary smarting of the eyes and respiratory tract; A mild eye irritant (no worse than hand soap); Prolonged skin contact may cause reddening; [CHRIS] An irritant; Inhalation may cause asthma symptoms or difficulty breathing; Toxic by skin absorption; Harmful by inhalation; [Aldrich MSDS] Isobutyl acrylate, stabilized (UN2527) has warning of explosive polymerization; [ERG 2016]
