Specification
The Triclosan is an organic compound with the formula C12H7Cl3O2. The IUPAC name of this chemical is 5-chloro-2-(2,4-dichlorophenoxy)phenol. With the CAS registry number 3380-34-5, it is also named as 2,4,4'-Trichloro-2'-hydroxydiphenyl ether. The product's categories are Intermediates; Miscellaneous; Organics; Biphenyl & Diphenyl Ether; Organic Building Blocks; Oxygen Compounds; Phenols. Besides, it should be stored in a dry dry and well-ventilated place.
The Triclosan is present in soaps, deodorants, toothpastes, shaving creams, mouth washes, and cleaning supplies, and is infused in an increasing number of consumer products, such as kitchen utensils, toys, bedding, socks, and trash bags. Triclosan has been shown to be effective in reducing and controlling bacterial contamination on the hands and on treated products. More recently, showering or bathing with 2% triclosan has become a recommended regimen for the decolonization of patients whose skin is carrying methicillin-resistant Staphylococcus aureus (MRSA) following the successful control of MRSA outbreaks in several clinical settings.
Physical properties about Triclosan are: (1)ACD/LogP: 5.17; (2)# of Rule of 5 Violations: 1; (3)ACD/LogD (pH 5.5): 5.17; (4)ACD/LogD (pH 7.4): 5.03; (5)ACD/BCF (pH 5.5): 5015.37; (6)ACD/BCF (pH 7.4): 3607.97; (7)ACD/KOC (pH 5.5): 15475.83; (8)ACD/KOC (pH 7.4): 11133.05; (9)#H bond acceptors: 2; (10)#H bond donors: 1; (11)#Freely Rotating Bonds: 3; (12)Polar Surface Area: 18.46 Å2; (13)Index of Refraction: 1.631; (14)Molar Refractivity: 69.26 cm3; (15)Molar Volume: 194.3 cm3; (16)Polarizability: 27.45×10-24cm3; (17)Surface Tension: 51.7 dyne/cm; (18)Density: 1.49 g/cm3; (19)Flash Point: 162.2 °C; (20)Enthalpy of Vaporization: 61.19 kJ/mol; (21)Boiling Point: 344.6 °C at 760 mmHg; (22)Vapour Pressure: 3.26E-05 mmHg at 25°C.
Uses of Triclosan: it can be used to produce 2-(2,4-dichloro-phenoxy)-4,5-dichloro-phenol at temperature of 20 °C. It will need reagent SO2Cl2. The yield is about 100%.
