Ethyl Acetoacetate
Ethyl Acetoacetate is a colourless to pale yellow liquid ester with a soft, fruity apple-like aroma and a faint sweet note that recalls overripe pome fruit. It is used as a flavour ingredient and as a versatile chemical building block.
The compound has the molecular formula C₆H₁₀O₃ and CAS number 141-97-9. It is the ethyl ester of acetoacetic acid and exists as an equilibrium mixture of keto and enol tautomers, with the keto form dominant at room temperature.
We source bulk Ethyl Acetoacetate from top China manufacturers for our partners. The manufacturer is in Zhejiang. A smaller requirement can ship in a combined container with other ingredients.
Please send the grade you need, the volume and your destination port, and we will come back with a solution and a price.

Common Markets Grades
Ethyl Acetoacetate falls into two main quality bands.
The technical grade carries an assay of 98 to 99 percent and serves the bulk synthesis market, where it acts as a starting material for pyrazolone dyes, agrochemicals, and pharmaceutical intermediates.
The FCC and FEMA flavour grade is purified to a minimum 99 percent assay with tight controls on colour, acidity, and water content. This grade meets the Food Chemicals Codex monograph and is the standard quality for flavour compounding.
Kosher and Halal certified lots are routinely available on request.
Applications
- Apple, pear, and quince flavour bases for soft drinks and fruit beverages

How We Help Source Ethyl Acetoacetate
Direct Factory Sourcing
We run the whole process: selecting the manufacturer from the top Chinese food ingredient producers, negotiating the price, verifying quality, and coordinating the logistics. You deal with us instead of with several factories at once.
Original Packaging and Documents from the Manufacturer
The manufacturer sends your Ethyl Acetoacetate out of its own factory in the original packing, through to your destination port. The COA, COO, MSDS, TDS and any certifications reach you from the manufacturer as well.
Free Samples and Lead Time
We send 100 to 500 g free for your own laboratory to test and you cover only the courier, usually within 2 to 3 working days. ETD is usually within 7 to 15 days once the order is confirmed, and we check that date against the factory's own manufacturing schedule before we give it to you.
Combined Shipment
We can load Ethyl Acetoacetate together with other ingredients such as Capsicum Oleoresin, Ethyl Maltol and White Pepper into one 20' FCL. If your quantity is small, we can also ship LCL.
Regulatory Status
Ethyl Acetoacetate is widely accepted as a flavour ingredient.
FEMA has assigned GRAS number 2415 for its use as a flavouring substance in food. The U.S. Food and Drug Administration lists it as a synthetic flavouring substance permitted in food under 21 CFR 172.515.
The European Food Safety Authority evaluated the substance as part of flavouring group FGE.10 and concluded that no safety concern arises at current levels of intake from use as a flavour. It carries FL number 09.612 in the Union list of flavourings.
The Council of Europe and the Japanese Ministry of Health, Labour and Welfare permit its use in food under their respective flavour regulations.
Pharmacopoeial monographs are not maintained because the substance is not itself a drug product, but reference standards exist from major analytical suppliers.
Manufacturing Process
Two industrial routes are practiced at scale.
The first and oldest route is the Claisen condensation of ethyl acetate with itself, catalysed by sodium ethoxide. The reaction yields ethyl acetoacetate, ethanol, and sodium acetate after acid workup. This route is energy intensive but uses a cheap, single feedstock.
The dominant modern route is the addition of ethanol to diketene. Diketene, generated by dimerization of ketene from acetic acid or acetone pyrolysis, reacts cleanly with anhydrous ethanol in the presence of a basic or acidic catalyst to give ethyl acetoacetate in over 95 percent yield. Lonza, Eastman, and several Chinese producers operate plants based on this chemistry.
Crude product is distilled under reduced pressure to separate light ends and high boilers, then polished through a final fractionation column to meet flavour-grade purity.
