DOT Classification: 3; Label: Flammable Liquid, Poison (UN 1228); DOT Class: 6.1; Label: Poison, Flammable Liquid (UN 3071)
The IUPAC name of Isopropanethiol is propane-2-thiol. With the CAS registry number 75-33-2, it is also named as 1-Methylethanethiol. The product categorie is thiol flavor. It is colorless liquid with a strong skunk-like odor and is miscible with ethanol and ether, soluble in acetone, slightly soluble in water. It may liberate hydrogen sulfide when mixed with an acid. When heated to decomposition it emits highly toxic fumes of SOx. Additionally, Isopropanethiol is used as a solvent and organic synthesis intermediate. Besides, it must be sealed in the container and stored in a cool, dry place.
The other characteristics of this product can be summarized as: (1)ACD/LogP: 1.60; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 1.6; (4)ACD/LogD (pH 7.4): 1.6; (5)ACD/BCF (pH 5.5): 9.6; (6)ACD/BCF (pH 7.4): 9.6; (7)ACD/KOC (pH 5.5): 175.74; (8)ACD/KOC (pH 7.4): 175.65; (9)#H bond acceptors: 0; (10)#H bond donors: 0; (11)#Freely Rotating Bonds: 1; (12)Index of Refraction: 1.428; (13)Molar Refractivity: 23.8 cm3; (14)Molar Volume: 92.4 cm3; (15)Polarizability: 9.43×10-24 cm3; (16)Surface Tension: 22.2 dyne/cm; (17)Enthalpy of Vaporization: 27.91 kJ/mol; (18)Vapour Pressure: 246 mmHg at 25°C; (19)Exact Mass: 76.034671; (20)MonoIsotopic Mass: 76.034671; (21)Topological Polar Surface Area: 1; (22)Heavy Atom Count: 4; (23)Complexity: 10.8.
Uses of Isopropanethiol: It reacts with 3-chloro-propene to get 3-isopropylsulfanyl-propene. This reaction needs reagent sodium hydroxide and solvent methanol at temperature of 0 °C. The reaction time is 1 hours. The yield is 90%.
