2-Acetyl Thiazole
2-Acetyl Thiazole is a pale yellow to amber liquid aroma chemical with the formula C₅H₅NOS and CAS number 24295-03-2. It delivers a warm popcorn note coupled with a distinctive roasted cereal and faintly bready character.
The compound is a member of the sulphur-nitrogen heterocyclic ketone family that defines much of the Maillard top in flavour work. It is dosed at parts-per-billion to low parts-per-million levels in finished food.
We source bulk 2-Acetyl Thiazole 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
The trade carries 2-Acetyl Thiazole as a neat liquid and as prepared dilutions.
The standard commercial grade is 98 percent minimum assay by gas chromatography, packed in amber glass under nitrogen. Larger volumes ship in lined stainless steel pails or drums.
One percent and 10 percent solutions in propylene glycol, triacetin, or ethanol are stocked for flavour benches where the neat material is too potent to weigh directly.
FCC and FEMA GRAS conforming material is the routine specification for food work. Kosher and Halal certificates exist on request.
Applications
- Popcorn flavours as the central roasted-cereal top note
- Bread, baked goods, and toasted crust profiles
- Coffee compounds for a roasted nutty layer
- Roasted nut flavours including peanut, hazelnut, and pistachio
- Cocoa, chocolate, and praline blends as a Maillard accent
- Meat and savory flavours where it bridges the sulphur core to the roasted top
- Beer, malt whisky, and dark spirit reconstructions
- Rice cracker, pretzel, and extruded cereal coatings
- Caramel, toffee, and butterscotch flavours for a roasted edge
- Tobacco flavouring as a casing top note
- Fine fragrance gourmand accords for popcorn, coffee, and praline themes
China Manufacturers of 2-Acetyl Thiazole

How We Help Source 2-Acetyl Thiazole
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 Thiazole 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 Thiazole 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 Thiazole is approved as a flavouring substance in all major regulated markets.
It carries FEMA GRAS number 3328 in the Flavour and Extract Manufacturers Association inventory.
In the European Union it is listed in the Union list of flavourings under FL number 15.024 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. JECFA has evaluated the sulphur-containing heterocyclic flavour group, including 2-Acetyl Thiazole, without raising safety concerns at current use levels.
Material conforms to the Food Chemicals Codex monograph. Kosher and Halal certifications are routinely provided.
Manufacturing Process
2-Acetyl Thiazole is made by synthesis on a pre-formed thiazole ring.
The most widely used route starts from 2-bromothiazole or 2-iodothiazole. Halogen-metal exchange with butyllithium at low temperature, followed by quenching with N-methoxy-N-methylacetamide (Weinreb amide) or acetic anhydride, installs the acetyl group cleanly at the 2-position.
An older route uses Friedel-Crafts acylation of thiazole with acetyl chloride and a Lewis acid catalyst, though regioselectivity is lower and downstream purification is heavier.
Crude product is purified by vacuum distillation under nitrogen. The finished liquid is filtered and packed under inert gas in light-shielded containers, since prolonged exposure to air and light can deepen the colour.
