Air & Water Reactions
Highly flammable. Water soluble.
Fire Hazard
Excerpt from ERG Guide 129 [Flammable Liquids (Water-Miscible / Noxious)]:

HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. (ERG, 2016)
Health Hazard
Very high vapor concentrations irritate eyes and upper respiratory tract. Continued contact with skin may cause irritation. (USCG, 1999)

Reactivity Profile
ISOPENTYL ALCOHOL  attacks plastics [Handling Chemicals Safely, 1980. p. 236]. Mixtures with concentrated sulfuric acid and strong hydrogen peroxide may cause explosions. Mixing with hypochlorous acid in water or water/carbon tetrachloride solution can generate isoamyl hypochlorites, which may explode, particularly on exposure to sunlight or heat. Mixing with chlorine would also yield isoamyl hypochlorites [NFPA 491 M, 1991]. Base-catalysed reactions with isocyanates can occur with explosive violence [Wischmeyer,1969].

Apart from the primary metabolite ethanol, several higher alcohols are formed at different levels, of which ISOPENTYL ALCOHOL  (Fig. 1B, descriptors: ‘alcoholic’, ‘vinous’, ‘sweet’) is the most abundant secondary metabolite and typically found well above its flavor threshold in beer. ISOPENTYL ALCOHOL  has also some banana flavor character and has been identified above its threshold in banana, orange, mango, pineapple and passion fruit 


ISOPENTYL ALCOHOL  is a banana oil or hot alcohol like flavour. It is very light but has a lingering taste and mouthfeel. It commonly occurs due to poor fermentation conditions – when the temperature is not correct or dissolved gases are not optimal.
