Ethyl Mercaptan CAS 75-08-1
Overview
Ethyl Mercaptan (systematically known as Ethanethiol, CAS: 75-08-1, Formula: C2H5SH) is a highly volatile liquid renowned for its extraordinarily pungent odor. This unique trait makes it the globally mandated warning odorant for odorless fuel gases like LPG and natural gas. Additionally, as a highly reactive thiol compound, it serves as a critical agrochemical intermediate and nucleophile in the synthesis of advanced organophosphate insecticides, pharmaceutical APIs, and polymer modifiers.
Product Description
Ethyl Mercaptan, also known as Ethanethiol, is a highly volatile liquid characterized by a penetrating, pungent odor detectable by humans at extreme trace levels (parts per billion). This unique property establishes it as the globally mandated warning odorant for odorless fuel gases like LPG and natural gas. Beyond public safety, the highly reactive sulfhydryl (-SH) group makes it a vital nucleophile and precursor in the synthesis of advanced agrochemicals and pharmaceuticals.
At Shandong Yinglang Chemical Co., Ltd., established in 2011, we supply bulk commercial volumes of Ultra-High Purity Ethyl Mercaptan to multinational utility companies and elite agrochemical formulators. Shipped globally under strict Class 3 Dangerous Goods regulations, our product is packaged in absolutely gas-tight, heavy-duty sealed containers to guarantee zero odor leakage and pristine chemical integrity upon delivery.
Due to its extreme volatility and specific applications in agrochemical synthesis and gas odorization, we maintain rigorous control over its physicochemical parameters and purity:

- Fuel Gas Odorant: The global standard warning agent. Injected at trace levels into odorless natural gas and LPG to provide an immediate olfactory warning of dangerous gas leaks.
- Agrochemical Synthesis: A vital sulfur-containing building block for the synthesis of highly effective organophosphate insecticides and systemic herbicides.
- Pharmaceutical Intermediates: Utilized in multi-step synthesis pathways leveraging the unique reactivity of the thiol group.
- Polymerization: Functions as a highly effective radical chain transfer agent to control molecular weight in advanced plastics.
When procuring highly volatile mercaptans, the integrity of the packaging is just as critical as the purity of the chemical. Even a microscopic vapor leak during ocean transit can trigger massive false gas-leak alarms, resulting in severe port lockdowns and immense financial penalties. Yinglang Chemical utilizes heavy-duty, nitrogen-purged steel drums equipped with specialized gas-tight bung seals. We guarantee absolute zero odor emission during global Class 3 transit, delivering a 99.0% pure, moisture-free nucleophile directly to your utility pipelines or synthetic reactors.
- Transport Classification: Classified as Class 3 (Flammable Liquid).
- UN Number: UN 2363 | Packing Group: I
- Handling Precautions: EXTREMELY FLAMMABLE. Flash point is -48°C. Intense, repulsive odor. Operators MUST handle in strictly enclosed, explosion-proof systems. Store in a heavily climate-controlled DG facility away from ignition sources.

FAQ
Q1: What documents and certifications do you provide?
A Standard shipment includes COA (Certificate of Analysis) and MSDS (SDS). We also provide ISO 9001 certification and support third-party inspections like SGS or BV upon request.
Q2: Do you provide custom synthesis or formulation services?
A Yes. If you have specific purity requirements or a unique formulation, our R&D team can provide custom synthesis and adjust the stabilizers/inhibitors to meet your technical specifications.
Q3: What are your terms of payment?
A
For Orders ≤ $1,000: 100% in advance.
For Orders > $1,000: 30% T/T in advance, and the balance before shipment or against the copy of B/L. Irrevocable L/C at sight is also acceptable for bulk orders.
Q4: How long is your price valid?
A Chemical prices fluctuate due to the changes in raw material costs and exchange rates. Please contact our sales team for the latest real-time quotation.
Q5: What packaging and shipping ports are available?
A
We normally ship from Qingdao, Shanghai, or Ningbo.
Standard packaging includes 200kg Drums or 1000kg IBC Totes. We ensure strict safety compliance for both general and hazardous chemical cargoes.
Q6: It's my first time importing chemicals — can you help?
A Absolutely. Importing chemicals requires specific documentation. Our experienced logistics team will assist you with the entire process, including handling customs clearance documents and arranging the most suitable shipping method.
