  • Beschreibung Methyl pentanoate, commonly known as methyl valerate, is the methyl ester of pentanoic acid (valeric acid) with a fruity odor.
    Methyl pentanoate is commonly used in fragrances, beauty care, soap, laundry detergents at levels of 0.1 – 1 % .
    In a very pure form ( greater than 99.5 % ) it is used as a plasticizer in the manufacture of plastics.
    It is also used as an insecticide.
  • Chemische Eigenschaften Methyl valerate has a pungent, green-fruity odor that is apple- and pineapple-like with a corresponding flavor at 1 0 – 5 0 ppm. May be prepared by direct esterification of the valeric acid with methanol in the presence of concentrated H2S04; note: this ester hydrolyzes readily.
  • Chemische Eigenschaften Methyl valerate has a pungent, green-fruity odor, apple and pineapple-like. It has a similar flavor at 10 to 50 ppm
  • Chemische Eigenschaften clear colorless liquid
  • Occurrence Reported found in small amounts in the essential oil from the fruits of Ananas sativus Schult. Also reported present in apple, coffee, honey, kiwi, melon, papaya, pineapple, strawberry, tea, wine, blackberry, baked potato, olive, starfruit, passion fruit, soursop, Bourbon vanilla, mountain papaya and naranjilla fruit.
  • synthetische By direct esterification of valeric acid with methanol in the presence of concentrated H2SO4. Note: This ester hydrolyzes readily
  • Aroma threshold values Detection: 20 to 89 ppb
  • Taste threshold values Taste characteristics at 20 ppm: sweet, ripe, fruity with sweaty, dairy and cheesy nuance
  • Synthesis Reference(s) Journal of the American Chemical Society, 97, p. 1180, 1975 DOI: 10.1021/ja00838a036
  • Allgemeine Beschreibung Clear colorless to yellowish oily liquid.
  • Air & Water Reaktionen Highly flammable. Insoluble in water.
  • Reaktivität anzeigen METHYL VALERATE 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. METHYL VALERATE reacts with oxidizing agents, bases and acids.
  • Brandgefahr METHYL VALERATE is flammable.
