1. 2-Thiophenethiol is primarily used as a chemical intermediate in pharmaceutical synthesis, including the production of the antihistamine drug pipethiadene and the matrix metalloproteinase inhibitor batimastat .
2. 2-Thiophenethiol CAS 7774-74-5 serves as a key aroma volatile in the meat-like Maillard reaction system and is used in biological studies to evaluate odorant changes in roasted hazelnuts .
3. 2-Thiophenethiol is utilized in organic synthesis as a building block for preparing various thiophene-based derivatives with potential anticancer, anti-inflammatory, and antimicrobial properties .
Packed in 25 kg per drum or based on customers' requirements.
1. 2-Thiophenethiol is synthetically produced via the gas-phase reaction of 2-chlorothiophene with hydrogen sulfide at elevated temperatures (510-570°C), with methanol as an initiator to improve yield and selectivity .
2. 2-Thiophenethiol CAS 7774-74-5 is also manufactured through industrial methods including the cyclization of butane, butadiene, or butenes with sulfur .
3. 2-Thiophenethiol can be synthesized via nucleophilic substitution reactions where a thiol group is introduced onto the thiophene ring .
1. 2-Thiophenethiol is classified as toxic if swallowed, in contact with skin, or if inhaled (H301+H311+H331), and causes skin and serious eye irritation (H315/H319) .
2. When handling 2-Thiophenethiol CAS 7774-74-5, wear protective gloves, eye protection, and face protection, and avoid breathing mists or vapors .
3. 2-Thiophenethiol is a combustible liquid with a flash point of 65°C (149°F); in case of fire, use dry chemical, carbon dioxide, or alcohol-resistant foam .
1. Store 2-Thiophenethiol at 0-10°C (refrigerated) in a tightly closed container, under inert gas, as 2-Thiophenethiol is air-sensitive .
2. Store 2-Thiophenethiol CAS 7774-74-5 in a cool, dry, well-ventilated place away from heat sources and incompatible materials .
3. For maximum recovery of 2-Thiophenethiol, centrifuge the original vial prior to removing the cap, and store stock solutions under inert atmosphere .
