Specification

The IUPAC name of p-Isopropylphenol is 4-propan-2-ylphenol. With the CAS registry number 99-89-8, it is also named as 1-Hydroxy-4-isopropylbenzene. It is white to beige crystalline solid which is slightly soluble in water, soluble in ethanol and ethyl ether. In addition, thischemical is toxic and flammable. When heated to decomposition it emits acrid smoke and fumes. So the storage environment should be ventilate, low-temperature and dry. Keep p-Isopropylphenol separate from oxidant.

The other characteristics of this product can be summarized as: (1)ACD/LogP: 2.82; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 2.82; (4)ACD/LogD (pH 7.4): 2.82; (5)ACD/BCF (pH 5.5): 81.99; (6)ACD/BCF (pH 7.4): 81.86; (7)ACD/KOC (pH 5.5): 815.63; (8)ACD/KOC (pH 7.4): 814.34; (9)#H bond acceptors: 1; (10)#H bond donors: 1; (11)#Freely Rotating Bonds: 2; (12)Index of Refraction: 1.525; (13)Molar Refractivity: 42.31 cm³; (14)Molar Volume: 137.9 cm³; (15)Polarizability: 16.77×10^-24 cm³; (16)Surface Tension: 35.7 dyne/cm; (17)Enthalpy of Vaporization: 46.3 kJ/mol; (18)Vapour Pressure: 0.147 mmHg at 25°C; (19)Rotatable Bond Count: 1; (20)Tautomer Count: 2; (21)Exact Mass: 136.088815; (22)MonoIsotopic Mass: 136.088815; (23)Topological Polar Surface Area: 20.2; (24)Heavy Atom Count: 10; (25)Complexity: 90.9.

Preparation of p-Isopropylphenol: It can be obtained by C9H11Li. This reaction needs reagent tBuOOH and Ti(OiPr)₄ and solvent diethyl ether at temperature of -78 °C. The reaction time is 12 hours. The yield is 80%.

Uses of p-Isopropylphenol: It is used in organic synthesis. For example: it can react with trichloromethane to get 2-hydroxy-5-isopropyl-benzaldehyde. This reaction which is Reimer-Tiemann reaction needs reagent sodium hydroxide and solvent ethanol and H₂O at temperature of 70 °C.

When you are using this chemical, please be cautious about it as the following:
It is not only harmful if swallowed, but also harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment. It may cause sensitization by skin contact and may cause burns. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. If you want to contact this product, you must wear suitable protective clothing, gloves and eye/face protection. In case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible.) And people should avoid release it to the environment.
