Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Journal of Research of the National Bureau of Standards (United States) called Optical rotation and atomic dimension for the four optically active 1-halo-2-methylbutanes, Author is Brauns, Dirk H., which mentions a compound: 616-14-8, SMILESS is CCC(CI)C, Molecular C5H11I, Recommanded Product: 616-14-8.
cf. C. A. 25, 2977. Detailed directions are given for the preparation of pure 2-methyl-1-butanol (I) and its F, Cl, Br and I derivatives. The following properties are described: I b. 128°, b50 65.7°, d420 0.8193, nD20 1.4107, sp. rotation for λ 5892.5 A. -5.756, for 5461 A. -6.835, for 5850 A. -5.78. The last 3 values were taken at about 20°. The corresponding values for the derivatives are: for 1-fluoro-2-methylbutane 55.9°, -, 0.7906, 1.3576, -8.865, -10.477, -8.87; for 1-chloro-2-methylbutane 100.45°, 27.7°, 0.8857, 1.4124, +1.644, +1.847, +1.68; for 1-bromo-2-methylbutane 121.6°, 45.0°, 1.2234, 1.4451, +4.043, +4.707, +4.09; and for 1-iodo-2-methylbutane -, 66.5°, 1.5253, 1.4977, +5.685, +6.626, +5.71. The differences in mol. rotation (Cl-F), (Br-Cl) and (I-Br) have the ratio 41:18:21.6, which agrees with the ratio of the differences of the radii of the respective neutral atoms.
《Optical rotation and atomic dimension for the four optically active 1-halo-2-methylbutanes》 provides a strategy for the preparation of materials with excellent comprehensive properties, which is conducive to broaden the application field of this compound(1-Iodo-2-methylbutane)Recommanded Product: 616-14-8.
