2-Acetyl Pyrazine
2-Acetyl Pyrazine is a crystalline aroma chemical with the formula C₆H₆N₂O and CAS number 22047-25-2. It carries one of the most recognizable Maillard signatures in the flavorist's palette: warm popcorn with a nutty roasted backbone.
The compound forms naturally during the cooking of cereals, the roasting of coffee and cocoa, and the baking of bread crust. It is used at trace levels, typically a fraction of a part per million in finished product.
We source bulk 2-Acetyl Pyrazine from top China manufacturers for our partners. The manufacturer is in Shandong. 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
Two main commercial forms of 2-Acetyl Pyrazine reach the market.
Crystalline material at 99 percent minimum assay is the reference grade. It ships as off-white to pale tan crystals or flakes, packed under nitrogen in light-shielded fibre drums or aluminium pouches.
A 10 percent solution in propylene glycol or triacetin is widely stocked for liquid flavour compounding, where the diluted form removes the need to weigh sub-gram quantities of the pure solid.
FCC and FEMA GRAS conforming material is the standard for food and beverage work. Kosher and Halal letters exist from most established suppliers.
Applications
- Popcorn and corn-snack seasoning systems where it delivers the buttered-popcorn top note at ppm levels
- Bread, crust, and baked-goods flavours that need an authentic oven-fresh signature
- Roasted nut profiles for peanut, hazelnut, almond, and pistachio reconstitutions
- Coffee compounds, both ground-roast and instant-style, as a nutty-roasted enhancer
- Cocoa and chocolate flavours where it lifts the dry roasted character
- Malt, beer, and whisky flavours for the cereal-toasted layer
- Savory and meat flavours as a Maillard top-note booster
- Tobacco casing and reconstituted-leaf formulations for a baked nutty lift
- Rice cracker, pretzel, and cereal coating flavours
- Dairy applications such as caramel, dulce de leche, and toffee where a roasted edge is wanted
- Fine fragrance and gourmand perfumery for popcorn, hazelnut, and praline accords

How We Help Source 2-Acetyl Pyrazine
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 2-Acetyl Pyrazine 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 2-Acetyl Pyrazine 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
2-Acetyl Pyrazine is recognised as a flavour ingredient in the major jurisdictions.
It carries FEMA GRAS number 3126 and is listed by the Flavour and Extract Manufacturers Association for use as a flavouring substance in food.
In the European Union it appears in the Union list of flavourings under FL number 14.012 and is permitted for general flavour use subject to good manufacturing practice.
The U.S. Food and Drug Administration recognises it as a synthetic flavouring substance under 21 CFR 172.515. The Council of Europe lists it in the active flavouring inventory, and JECFA evaluated the pyrazine flavouring group without raising safety concerns at current use levels.
The compound conforms to the Food Chemicals Codex monograph for 2-Acetyl Pyrazine. Kosher and Halal certifications are routinely available.
Manufacturing Process
Industrial 2-Acetyl Pyrazine is made by synthetic routes that build the acetyl group onto a pre-formed pyrazine ring.
The most common laboratory and pilot-scale method starts from 2-methylpyrazine. Selective oxidation or acylation followed by purification gives the target ketone. Plant-scale work usually replaces this with a Grignard or organolithium addition of methyl onto 2-cyanopyrazine, followed by hydrolysis of the resulting imine.
An alternative route condenses ethylenediamine with a 1,2-diketone such as 2,3-butanedione under oxidative conditions, building the pyrazine ring with the acetyl group already in place.
Crude product is purified by vacuum distillation and recrystallisation from a hydrocarbon or alcohol solvent. The finished crystals are dried and packed under inert gas to prevent darkening on long storage.
