2-Methyl-3-Tetrahydrofuranthiol
2-Methyl-3-Tetrahydrofuranthiol is a colourless to pale yellow liquid aroma chemical with the formula C₅H₁₀OS and CAS number 57124-87-5. It carries a soft cooked-meat character with a clean sulphur note and a brothy undertone.
It is the saturated cousin of 2-methyl-3-furanthiol, with the furan ring fully hydrogenated to tetrahydrofuran. This change rounds the profile, making it gentler and more savory than the sharper roasted top of the unsaturated analog.
We source bulk 2-Methyl-3-Tetrahydrofuranthiol 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
Buyers take 2-Methyl-3-Tetrahydrofuranthiol either as neat liquid or as ready-to-dose dilutions.
The standard commercial grade is 97 percent minimum assay by gas chromatography, packed in amber glass under nitrogen. The presence of two stereocenters means commercial material is a mixture of cis and trans diastereomers, with the cis isomer generally regarded as more aroma-active.
One percent and 10 percent dilutions in triacetin, propylene glycol, or refined vegetable oil are common for flavour compounding because the neat material is too potent to weigh directly.
FCC and FEMA GRAS conforming material is the routine specification. Kosher and Halal certifications exist.
Applications
- Cooked beef and stew flavours as a brothy meaty layer
- Boiled chicken and white-meat broth reconstructions
- Pork, ham, and bacon compounds for a cooked-meat undertone
- Yeast extract and HVP-style savory bases
- Bouillon, gravy, and culinary stock flavours
- Snack seasonings for meat-flavoured chips and extrusion products
- Pet food palatants for boiled-meat realism
- Plant-based meat analogs to deliver authentic cooked character
- Reaction-flavour finishing where it rounds and smooths the sulphur profile
- Sulfury accents in cooked vegetable flavours such as cabbage and onion
- Co-use with 2-methyl-3-furanthiol to balance roasted top against brothy depth

How We Help Source 2-Methyl-3-Tetrahydrofuranthiol
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-Methyl-3-Tetrahydrofuranthiol 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-Methyl-3-Tetrahydrofuranthiol 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-Methyl-3-Tetrahydrofuranthiol is approved as a flavouring substance in the major regulated markets.
It carries FEMA GRAS number 3408 under the Flavour and Extract Manufacturers Association.
The European Union lists it in the Union list of flavourings as FL number 15.072, permitted for general flavour use under good manufacturing practice.
The U.S. Food and Drug Administration recognises it as a synthetic flavouring substance under 21 CFR 172.515. JECFA has reviewed the saturated furan-thiol flavouring group and concluded no safety concern at the very low use levels typical of this material.
Material conforms to the Food Chemicals Codex monograph. Kosher and Halal certifications are routinely provided.
Manufacturing Process
Industrial 2-Methyl-3-Tetrahydrofuranthiol is produced by catalytic hydrogenation of 2-methyl-3-furanthiol or by independent synthesis from saturated building blocks.
Selective hydrogenation of the furan ring of 2-methyl-3-furanthiol under controlled hydrogen pressure with a palladium or nickel catalyst gives the tetrahydrofuran product directly. Reaction conditions must be tuned to spare the thiol from desulfurization, which is the main side reaction.
An alternative route starts from 2-methyltetrahydrofuran-3-one. Reduction of the ketone to the corresponding alcohol followed by conversion to the thiol (for example through a thioacetate intermediate and hydrolysis) delivers the target molecule in defined stereochemistry.
Crude product is purified by vacuum distillation under nitrogen and stabilised with a trace antioxidant. The finished liquid is packed under inert gas to limit oxidative dimerization on storage.
