Isobutyl Formate is a synthetic flavoring agent that is a stable,
colorless liquid of fruity odor. storage should be in glass or tin
containers. it is used in fruit flavors such as pear, raspberry, and
other berry flavors with applications in beverages, ice cream, candy,
and baked goods at 2–18 ppm. | [CAS DataBase Reference]

Hazard Information | Back Directory | [General Description]
A colorless liquid. Less dense than water. Flash point 60°F. Vapors heavier than air. Vapors may be narcotic and irritating in high concentrations. Used as a solvent and to make perfumes. | [Reactivity Profile]
ISOBUTYL FORMATE(542-55-2) is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. | [Air & Water Reactions]
Highly flammable. Soluble in water. | [Health Hazard]
May cause toxic effects if inhaled or absorbed through skin. Inhalation or contact with material may irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution. | [Fire Hazard]
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. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. | [Description]
Isobutyl formate has a fruity, ether-like odor and a sweet taste
reminiscent of rum. Isobutyl formate may be prepared from isobutyl alcohol and carbon monoxide in the presence of sodium isobutylate at 110°C and 400 atm. | [Chemical Properties]

Reported found in pineapple, apple, vinegar, wheat bread, beer, cognac and rum. | [Definition]
ChEBI: 2-Methylpropyl formate is a carboxylic ester. | [Preparation]
From isobutyl alcohol and carbon monoxide in the presence of sodium isobutylate at 110°C and 400 atm | [Taste threshold values]
Taste characteristics at 10 ppm: slightly sweet, fresh, gives lift, fruity | [Biochem/physiol Actions]
Taste at 10 ppm | [Purification Methods]
Wash the formate with saturated aqueous NaHCO3, in the presence of saturated NaCl solution until no further reaction occurs, then with saturated aqueous NaCl, dry (MgSO4) and fractionally distil it. [Beilstein 2 H 21, 2 I 18, 2 II 30, 2 III 41, 2 IV 29.] |
