Specification

The 2-Bromopropene, with the CAS registry number 557-93-7, is also known as 2-Bromo-1-propene. It belongs to the classification code of Mutation Data. Its EINECS registry number is 209-185-4. This chemical's molecular formula is C₃H₅Br and molecular weight is 120.98. What's more, its IUPAC name is called 2-Bromoprop-1-ene. It should be stored in a cool, dry and well-ventilated place.

Physical properties about 2-Bromopropene are: (1)ACD/LogP: 1.989; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 1.99; (4)ACD/LogD (pH 7.4): 1.99; (5)ACD/BCF (pH 5.5): 19.11; (6)ACD/BCF (pH 7.4): 19.11; (7)ACD/KOC (pH 5.5): 287.60; (8)ACD/KOC (pH 7.4): 287.60; (9)#H bond acceptors: 0; (10)#H bond donors: 0; (11)#Freely Rotating Bonds: 0; (12)Polar Surface Area: 0 Å²; (13)Index of Refraction: 1.452; (14)Molar Refractivity: 23.247 cm³; (15)Molar Volume: 86.132 cm³; (16)Polarizability: 9.216×10^-24cm³; (17)Surface Tension: 23.103 dyne/cm; (18)Density: 1.405 g/cm³; (19)Flash Point: -7.691 °C; (20)Enthalpy of Vaporization: 27.992 kJ/mol; (21)Boiling Point: 48.399 °C at 760 mmHg; (22)Vapour Pressure: 324.193 mmHg at 25 °C.

Uses of 2-Bromopropene: (1) it is used as refrigerant and can be used in organic synthesis; (2) it is used to produce other chemicals. For example, it can react with nonanal to get 2-methyl-undec-1-en-3-ol. This reaction needs reagent chromium(II) chloride and solvent dimethylformamide at temperature of 25 °C. The reaction time is 3 hours. The yield is 62 %.

-Bromopropene can react with nonanal to get 2-methyl-undec-1-en-3-ol.

When you are dealing with this chemical, you should be very careful. This chemical may cause inflammation to the skin or other mucous membranes. And it is irritating to eyes, respiratory system and skin. It may catch fire in contact with air, only need brief contact with an ignition source and have a very low flash point or evolve highly flammable gases in contact with water. Therefore, you should wear suitable protective clothing and can not breathe the gas/fumes/vapour/spray. In case of contacting with eyes, you should rinse immediately with plenty of water and seek medical advice.

You can still convert the following datas into molecular structure:
(1) SMILES: CC(=C)Br
(2) InChI: InChI=1S/C3H5Br/c1-3(2)4/h1H2,2H3
(3) InChIKey: PHMRPWPDDRGGGF-UHFFFAOYSA-N
