Iodoform Specification

Iodoform, with the CAS registry number 75-47-8, is also named as Triiodomethane. It belongs to the product category of Organics. Its EINECS number is 200-874-5. This chemical's molecular formula is CHI3 and molecular weight is 393.73. What's more, its systematic name is Iodoform. Its classification codes are: (1)Drug / Therapeutic Agent; (2)Mutation data; (3)Tumor data.This chemical is stable at common pressure and temperature, and it should be sealed and stored in a cool and dry place. Moreover, it should be protected from oxides, heat and fire. It is occasionally used as a disinfectant.

Physical properties of Iodoform are: (1)ACD/LogP: 3.118; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 3.12; (4)ACD/LogD (pH 7.4): 3.12; (5)ACD/BCF (pH 5.5): 138.00; (6)ACD/BCF (pH 7.4): 138.00; (7)ACD/KOC (pH 5.5): 1183.94; (8)ACD/KOC (pH 7.4): 1183.94; (9)#H bond acceptors: 0; (10)#H bond donors: 0; (11)#Freely Rotating Bonds: 0; (12)Index of Refraction: 1.851; (13)Molar Refractivity: 45.549 cm3; (14)Molar Volume: 101.897 cm3; (15)Polarizability: 18.057×10-24cm3; (16)Surface Tension: 66.8 dyne/cm; (17)Density: 3.864 g/cm3; (18)Flash Point: 128.988 °C; (19)Enthalpy of Vaporization: 46.821 kJ/mol; (20)Boiling Point: 250.668 °C at 760 mmHg; (21)Vapour Pressure: 0.03 mmHg at 25°C.

Preparation of Iodoform: this chemical can be synthesized in the haloform reaction by the reaction of iodine and sodium hydroxide with any one of these four kinds of organic compounds: (i) a methyl ketone: CH3COR, acetaldehyde, ethanol, and certain secondary alcohols (CH3CHROH, where R is an alkyl or aryl group).

Uses of Iodoform: it can be used to produce 1,1-diiodo-octan-2-ol at the temperature of 0 °C. It will need reagents samarium iodide, 1 M HCl and solvent tetrahydrofuran with the reaction time of 45 min. The yield is about 60%.

Iodoform can be used to produce 1,1-diiodo-octan-2-ol at the temperature of 0 °C

When you are using this chemical, please be cautious about it as the following:
This chemical is harmful by inhalation, in contact with skin and if swallowed. It is irritating to eyes, respiratory system and skin. You should not breathe dust. In case of contact with eyes, you should rinse immediately with plenty of water and seek medical advice. When using it, you need wear suitable protective clothing, gloves and eye/face protection.
