What is 2-Propanethiol CAS 75-33-2?
2‑Propanethiol (Isopropyl mercaptan, CAS 75‑33‑2) is a thiol compound with a very strong odor characteristic, which is widely used in natural gas odorization, petrochemical analysis and polymer synthesis. Its extremely high flammability and toxicity require users to strictly comply with dangerous goods safety regulations, wear appropriate PPE and operate in a well-ventilated environment.
2-Propanethiol CAS 75-33-2 Use
1. Gas Odorant
Due to its extremely low olfactory threshold (about 0.3 ppb) and extremely strong, pungent sulfur smell (similar to the smell of rotten eggs or skunk), 2-Propanethiol is often used as:
Natural gas, liquefied petroleum gas (LPG) odorant for leak detection
Mixed with other mercaptans such as ethyl mercaptan and tert-butyl mercaptan to enhance olfactory performance
2. Gas chromatography and chemical analysis standards (Analytical Reagent)
In petrochemical and chemical laboratories, 2-Propanethiol is also often used as:
Gas chromatography quantitative standards (for detecting sulfides and analyzing natural gas components)
3. Organic synthesis intermediates (Chemical Intermediate)
2-Propanethiol contains active thiol (–SH) groups, which can participate in a variety of organic synthesis reactions and are widely used in:
Polymer modifier: used to prepare sulfur-containing polyols, modified resins, and rubber additives.Pharmaceutical synthesis: used as a starting reagent or an introducer in the synthesis of certain sulfur-containing drugs and pesticide precursors
Sulfur modifier for functionalized coatings or catalyst carriers
4. Laboratory reagents and odor research (R&D and Odor Chemistry)
Used for olfactory testing, odor research, and olfactory molecular threshold experiments.Commonly used in universities and research institutions to conduct sulfide reaction mechanism or odor control research
2-Propanethiol CAS 75-33-2 safety
Flammability: Highly flammable, flash point about -31°C, vapor can form explosive mixture with air
Health hazards: Inhalation can cause dizziness, nausea, and breathing difficulties; contact with skin may cause allergic dermatitis; irritating to eyes
Environmental effects: Extremely toxic to aquatic life, with acute and chronic water toxicity (Aquatic Acute 1, Aquatic Chronic 1)
GHS hazard labels: GHS02, GHS07, GHS09; Signal word: Danger; Related H statements include H225, H317, H410
