Tert‑Butyl Mercaptan, also named 2‑methyl‑2‑propanethiol, carries the CAS number 75‑66‑1 and the molecular formula C4H10S. At room temperature it appears as a colour‑less, transparent liquid that is slightly soluble in water but fully miscible with ethanol, ether and heptane. The compound has a measured density of 0.80 g cm‑3 and a flash point of - 26 °C, indicating high flammability. Its boiling range of 62 °C to 65 °C and melting point of - 1.1 °C are typical for this class of thiols.
Suppliers usually offer the chemical in purity grades of 99 % or higher, which is essential for reliable performance in synthesis routes. Standard bulk packaging consists of 200 L steel drums or ISO tanks that comply with UN hazardous‑material regulations for Class 3 liquids. Recommended storage conditions keep the product below 30 °C in a well‑ventilated area, with secondary containment to prevent accidental release. The material’s strong mercaptan odor makes it valuable as an odorant in LPG and natural‑gas pipelines for leak detection.
Primary users include manufacturers of agro‑chemical intermediates, specialty polymers and pharmaceutical precursors who need a dependable thiol source. Trade can be arranged on FOB, CIF or DAP terms, with the supplier prepared to ship in accordance with hazardous‑material freight guidelines. Prospective buyers should request the latest safety data sheet, a certificate of analysis and confirmation of any ISO or SGS certifications before finalising the purchase.

Before confirming a purchase, ensure that the supplier can furnish a current certificate of analysis, safety data sheet and any relevant ISO or SGS certifications for the specific batch. Verify that the product’s purity, density and flash‑point data match your regulatory and process requirements. If possible, obtain a small trial quantity to validate performance in your application before scaling up.
Transportation of Tert‑Butyl Mercaptan generally follows hazardous‑material freight rules under INCOTERMS such as FOB, CIF or DAP. The supplier ships the chemical in steel drums or ISO tanks, so coordinate with a freight forwarder experienced in handling Class 3 liquids and confirm that customs paperwork includes the UN number, flash‑point and proper hazard labeling. Payment arrangements are typically negotiated via letter of credit or advance payment and should be detailed in the sales contract.
Upon receipt, inspect containers for leaks, dents or corrosion and compare the batch’s certificate of analysis against the agreed specifications. Conduct independent verification, such as GC testing, if your quality system requires additional confirmation of purity. Retain all documentation - including the SDS, test reports and shipping records - to demonstrate compliance with import regulations and to support any subsequent quality audits.
